Description

Low-power broadband high-speed preamplification amplitude phase shift modulation / demodulation communication system

[0001] An embodiment of the present invention relates to a method for a stable low-power broadband high-speed PEAPSK modulation and demodulation communication system and the configuration of the circuit thereof, wherein the high-frequency components of two binary data signals are pre-amplified (PE) by two types of data signals, and the data signals are amplitude-modulated (AM) at a baseband carrier frequency to generate a signal, which is then phase-modulated into one of the two binary data signals to communicate as a PEAPSK signal.

[0002] Since the PEAPSK (Pre-Emphasis Amplitude Phase Shift Keying) signal is a signal formed by combining a two-sided band signal in which the carrier is suppressed by a Phase Shift Keying (PSK) signal and a two-sided band signal in which the carrier is transmitted by an Amplitude Shift Keying (ASK) signal, asynchronous demodulation of the ASK signal is easy, but the problem of Intersymbol Interference (ISI) caused by time domain processing is solved by using the first binary data that has been pre-amplified (PE), and the demodulation of the PSK signal can be done asynchronously using a recently invented method, but the error problem caused by attenuation of high-frequency components due to bandwidth limitations in the transmission channel is solved by using the second binary data that has been pre-amplified.

[0003] The data input signal of the existing ASK signal is a square wave, and since high harmonic components included in the rising and falling edges are lost significantly during transmission, the DRCF (Data Rate to Carrier Frequency) ratio is low at 10% or less due to the limitation of the data transmission speed. However, in the embodiment of the present invention, the PEASK (Pre-Emphasis Amplitude Shift Keying) modulation signal is used by pre-amplifying the data signal into a positive pulse in the rising edge portion and a negative pulse in the falling edge portion, so it becomes a PEASK demodulation method that increases the DRCF ratio to 100% even with an asynchronous detector using a full-wave rectifier and a first-order low-pass filter.

[0004] The demodulation of existing PSK signals generally uses a cost loop, but it consumes a lot of power and has limitations in transmission speed due to the use of a feedback loop, which is a complex circuit including an internal oscillator. Additionally, the asynchronous DPSK (Differential Phase Shift Keying) demodulation circuit consumes a lot of power due to the internal oscillator and integrator, and the semiconductor chip area containing the complex circuit increases, resulting in low yield and high manufacturing costs. Furthermore, since data is transmitted in packet units, there is a limitation in transmission speed because the entire packet containing the error is discarded even if only one bit error occurs within the packet. In the embodiment of the present invention, since the high harmonic components generated when the carrier phase changes at the rising edge and falling edge portions of the data cause significant loss during transmission in the PEPSK (Pre-Emphasis Phase Shift Keying) modulated signal, the embodiment of the present invention uses an asynchronous PEPSK demodulation method that pre-amplifies the positive and negative pulses for an arbitrary period of the carrier at the rising edge and falling edge portions of the data signal, thereby achieving high transmission speed and stability.

[0005] Regarding ASK modulation / demodulation devices, Korean Registered Patent No. 10-1900856 describes a pre-amplified ASK transmitter and a demodulation circuit device that generates demodulated data at a detector in a receiver. Regarding PSK modulation / demodulation devices, Korean Registered Patent No. 10-2121219 describes a modulation and demodulation circuit device that performs stably through a synchronization signal generation unit in a demodulation device. Regarding PSK demodulation circuits, Korean Registered Patents No. 10-1578303 and No. 10-1623275 describe an asynchronous demodulation method that is free of an internal oscillator and allows the use of a Data Error Correction method.

[0006] The embodiment of the present invention aims to provide a PEAPSK modulation / demodulation circuit and a method thereof that overcomes the limitations and problems associated with transmission speed, stability, circuit complexity, and power consumption in PEAPSK modulation / demodulation schemes. Specifically, the problem of transmission speed limitations, error rates, and stability is caused by bandwidth limitations in a hybrid modulation / demodulation system of ASK (Amplitude Shift Keying) and PSK (Phase Shift Keying). This is achieved by communicating through phase shift modulation using a preamplified amplitude modulation (PEAM) baseband carrier, which is amplitude-modulated with a preamplified data signal synthesized by preamplifying two types of data respectively.

[0007] Accordingly, we intend to implement a circuit that improves the system by enhancing stability and transmission speed, by supplementing the communication system with a PEAPSK transmitter circuit that phase-modulates the PEAM baseband carrier with the second data signal. This circuit facilitates the provision of a simple and stable asynchronous demodulation circuit and method that transmits broadband binary data signals at high speed and is low-power. Specifically, to solve the ISI (inter-symbol interference) problem of the ASK (amplitude shift key) modulation / demodulation system, a first preamplified signal that emphasizes the high-frequency component of the first data signal and a second preamplified signal that emphasizes the edge signal of the second data signal to solve the bandwidth limit of the PSK (phase shift key) modulation / demodulation system are combined and amplitude-modulated by a signal generated by amplitude-modulating the baseband carrier, i.e., a PEAPSK transmitter circuit.

[0008] In the configuration of a PEAPSK modulation / demodulation method, a PEAM baseband carrier signal amplitude-modulated using a preamplified data tdapPE signal, which is a composite of a tdPE signal obtained by preamplifying the first binary data aDATA signal and a tdPEE signal obtained by preamplifying the edge signal of the second binary data pDATA signal, is used as the baseband carrier of a BPSK modulator, and when the phase of the PEAM baseband carrier is changed by the second binary data signal, a PEAPSK baseband modulation signal is generated, and a preamplified amplitude phase shift modulation transmitter that generates and outputs a PEAPSK RF transmission signal by loading the PEAPSK baseband modulation signal onto an RF (Radio Frequency) carrier; and a transmitter capable of transmitting the PEAPSK RF transmission signal with distortion through a wire channel or a wireless channel; A low-power broadband high-speed preamplifier amplitude phase shift demodulation and data clock recovery unit comprising: an asynchronous binary phase shift demodulator (BPSK Demodulator) that converts a transmission signal, i.e., a PEAPSK RF reception signal that may be distorted through the transmission unit, into a PEAPSK baseband modulation signal through an RF Carrier Mixer; separates the modulation signal into lower sideband and upper sideband analog signals; demodulates the second binary data pDATA using an asynchronous binary phase shift demodulator (BPSK Demodulator) that matches the sideband analog signals to a preset phase; generates a data clock pCLOCK for the recovered pDATA using the signal digitized from the lower sideband analog signal and the demodulated second binary data; generates a data clock aCLOCK for the recovered aDATA by synchronizing with pCLOCK; and generates the recovered data aDATA by synchronizing the binary data demodulated by asynchronous envelope detection with aCLOCK. A modulation and demodulation communication system may be provided.

[0011] It may include a baseband binary phase shift modulator (Baseband BPSK Modulator) that generates a PEAPSK modulated signal by loading the second binary data signal onto a PEAM baseband carrier generated by the baseband amplitude modulator, an RF Carrier Mixer that generates a PEAPSK RF transmission signal by loading the PEAPSK modulated signal onto an RF Carrier, and a transmitting side bandpass filter (BPF).

[0012] In another aspect, the transmission unit may include a wire channel or a wireless channel to which a PEAPSK-modulated RF signal is transmitted.

[0013] In another aspect, the asynchronous amplitude phase shift demodulation and data clock recovery unit may include a mixer that converts a bandwidth-limited PEAPSK RF received signal through a receiver-side BPF into a PEAPSK baseband signal using an RF carrier frequency, and a baseband BPF.

[0014] It may include a low-pass filter (LPF) for separating a lower sideband analog signal from the PEAPSK baseband signal, a high-pass filter (HPF) for separating an upper sideband analog signal, a phase aligner for aligning the sidebands to a preset phase, and an asynchronous BPSK demodulator for demodulating the second binary data signal using a pulse generated at a phase change portion which is the output of the phase aligner.

[0015] It may include a comparator that converts the lower sideband analog signal into a lower sideband digital signal, and a pCLOCK recovery circuit that recovers the data clock RECOVERED pCLOCK using the lower sideband digital signal and the demodulated data RECOVERED pDATA.

[0017] In a PEAPSK modulation and demodulation method, a signal obtained by pre-amplifying the high-frequency component of the first binary data signal and a signal obtained by pre-amplifying the high-frequency component of the second binary data signal is used as the baseband carrier of an amplitude-modulated PEAM baseband carrier signal of a BPSK modulator, and when the phase of the PEAM baseband carrier is changed by the second binary data signal, a PEAPSK baseband modulation signal is generated, and a pre-amplified amplitude phase shift modulation transmission step is used to generate and transmit a PEAPSK RF transmission signal by loading the PEAPSK baseband modulation signal onto an RF carrier; and a transmission step in which the PEAPSK RF transmission signal can be transmitted with distortion through a wired or wireless path. A low-power broadband high-speed preamplified amplitude phase shift modulation and demodulation communication system may be provided, comprising an asynchronous amplitude phase shift demodulation and data clock recovery step, wherein a transmission signal that may be distorted through the above transmission step, i.e., a PEAPSK RF reception signal, is converted into a PEAPSK baseband modulation signal through an RF Carrier Mixer, the modulation signal is separated into lower sideband and upper sideband analog signals, and the second binary data pDATA is demodulated using an asynchronous BPSK demodulator that matches the sideband analog signals to a preset phase, a recovered data clock pCLOCK is generated using a signal that digitizes the lower sideband analog signal and the demodulated second binary data, a recovered data clock aCLOCK is generated by synchronizing with the pCLOCK, and a recovered data aDATA is generated by synchronizing the binary data demodulated by asynchronous envelope detection with the aCLOCK.

[0018] Through an embodiment of the present invention, a PEAPSK modulation and demodulation communication system and method for low power can be provided, which transmits broadband data more stably and quickly than an ASK communication system or a PSK communication system.

[0019] In addition, it provides a modulation and demodulation method applicable to low-power high-speed wired and wireless communication devices, and is suitable for implementing a System on Chip (SoC), offering high convenience and cost-effectiveness.

[0031] The configuration and modulation / demodulation method of the PEAPSK modulation / demodulation communication system will be explained in detail below with reference to the attached drawings.

[0032] FIG. 1 illustrates a circuit diagram for explaining the configuration of a low-power broadband preamplifier amplitude phase shift (PEAPSK) modulation and demodulation communication system in an embodiment of the present invention. To explain the configuration of the circuit as shown in FIG. 1, the PEAPSK modulation and demodulation circuit may be configured to include a preamplifier amplitude phase shift modulation transmitter (110), a transmitter (120), and an asynchronous amplitude phase shift demodulation and data clock recovery unit (130).

[0033] First, the preamplified amplitude phase shift modulation transmitter (110) may include circuits that preamplify the high-frequency component of the first binary data aDATA signal to generate a multilevel data tdPE signal, namely a level-shifter, an inverter, a circuit that delays by Tb, which is one period of the first clock aCLOCK signal, and a circuit that synthesizes the t(n) signal and the t(n-1) signal; a circuit that preamplifies the high-frequency component of the second binary data pDATA signal for a preset time to generate a data edge tdPEE signal; a preamplified synthesis circuit that generates a preamplified data tdapPE signal by synthesizing the preamplified multilevel data signal and the preamplified data edge signal; and a baseband amplitude modulator that carries the preamplified synthesis signal generated through the preamplified synthesis circuit on a baseband carrier with amplitude modulation, and the preamplified synthesis circuit and the baseband It may include a binary phase shift modulator that generates a PEAPSK baseband modulation signal by loading the second binary data signal onto a PEAM baseband carrier generated through an amplitude modulator, an RF Carrier Mixer that generates a PEAPSK RF transmission signal by loading the PEAPSK baseband modulation signal onto an RF Carrier, and a transmitting side BPF.

[0034] Among these, the preamplifier circuits inputting the first binary data signal synthesize the t(n) signal and the t(n-1) signal, wherein the preamplifier multilevel data tdPE signal, which emphasizes the rising and falling edges containing high-frequency components of the binary data signal, is a four-level signal emphasizing high-frequency components, and the preamplifier data edge tdPEE signal, which emphasizes the rising and falling edges containing high-frequency components of the second binary data signal for a preset time through the preamplifier circuit inputting the second binary data, is a three-level signal emphasizing high-frequency components; and the transmission signal, which is loaded onto the RF Carrier again to transmit the PEAPSK baseband modulated signal generated by carrying the second binary data signal on the binary phase shift modulator on the PEAM baseband carrier signal generated by amplitude modulating the preamplifier data tdapPE signal (combining the preamplifier multilevel data signal and the preamplifier data edge signal) on the baseband carrier, is the high frequency of the data By emphasizing the components, the ISI problem arising from the high-frequency loss of the transmission unit and the envelope detection used for asynchronous amplitude shift demodulation is resolved, and the ISI problem is resolved by asynchronous binary phase shift demodulation of the PEAPSK RF reception signal, which is distorted due to bandwidth limitation through the receiver-side BPF, thereby stabilizing data demodulation and reducing bit errors.

[0035] The transmission unit (120) may be configured to include a wired path (Wire Channel) or a wireless path (Wireless Channel) through which a PEAPSK modulated RF transmission signal is transmitted.

[0037] Here, a PEAPSK Baseband signal is generated from a PEAPSK RF reception signal with limited bandwidth through a receiving BPF, and the PEAPSK Baseband signal is separated into analog signals of the lower sideband (LSB) and upper sideband (USB). Then, the analog signals of the sidebands are aligned to a preset phase to generate positive pulse and negative pulse signals occurring in the phase change portion of the PEAPSK Baseband signal, thereby allowing asynchronous demodulation of a pDATA signal, such as the second binary data. Additionally, a data clock pCLOCK can be restored using the lower sideband digital signal obtained by digitizing the lower sideband analog signal and the demodulated pDATA signal. Furthermore, a data clock aCLOCK synchronized with pCLOCK can be restored, and an aDATA signal, such as the first binary data, can be demodulated using asynchronous envelope detection.

Through the configuration of the PEAPSK modulation / demodulation communication system described in FIG. 1, a preamplified amplitude phase shift modulation transmission step (210), a transmission step (220), and an asynchronous amplitude phase shift demodulation and data clock recovery step (230) can be performed.

[0050] In the above pre-amplified amplitude phase shift modulation transmission step (210), a multilevel data tdPE signal is generated by synthesizing a t(n) signal, which is level shifted from the first binary data aDATA signal, and a t(n-1) signal, which is inverted from the aDATA signal and delayed by Tb, which is one period of the clock aCLOCK signal, to pre-amplify the multilevel data tdPE signal. Then, a PEAPSK baseband modulation signal is generated by using amplitude modulation on the baseband carrier signal to binary phase shift modulate the PEAM baseband carrier signal, which is the output of a data edge converter that pre-amplifies the high-frequency component of the second binary data pDATA signal for a preset time, and the pre-amplified data tdapPE signal, which is the output of the data edge converter that pre-amplifies the high-frequency component of the second binary data pDATA signal, and the PEAPSK baseband modulation signal, which is binary phase shift modulated with the second binary data pDATA signal. After generating the PEAPSK baseband modulation signal, it can be converted into a PEAPSK RF signal through an RF Carrier Mixer and a transmitting side BPF and transmitted.

[0051] First, synthesizing the t(n) signal and the t(n-1) signal through the preamplifier circuit ensures stable transmission of the data aDATA signal by resolving the ISI problem that inevitably occurs during conventional ASK demodulation when the data aDATA signal is restored at the receiver's amplitude shift demodulator using the tdPE signal, which emphasizes high-frequency components with four levels, and the preamplified signal that emphasizes the rising and falling edges containing high-frequency components of the first binary data aDATA signal for a preset time, and the tdPEE signal, which emphasizes high-frequency components with three levels, ensures stable transmission of the data pDATA signal by resolving the ISI problem that may occur during conventional PSK demodulation when the data pDATA signal is restored at the receiver's phase shift demodulator, and the preamplified data tdapPE signal, which is the synthesis of the tdPE signal and the tdPEE signal The transmission signal, which is carried on the RF Carrier again to transmit the PEAPSK baseband signal generated by carrying the binary data signal on the PEAM baseband carrier signal generated by amplitude modulation on the baseband carrier through the binary phase shift modulator, emphasizes the high-frequency components of the data and resolves the ISI problem by asynchronously performing binary phase shift demodulation on the PEAPSK RF reception signal, which is distorted due to bandwidth limitations through the high-frequency loss of the transmission stage (220) and the receiving side BPF, thereby stabilizing data demodulation and reducing bit errors.

[0052] In the transmission step (220), when transmitting the PEAPSK RF transmission signal, which is the signal output from the preamplified amplitude phase shift modulation transmission step (210), the path may be a wired path or a wireless path depending on the path, and depending on the characteristics of the path, a signal distorted compared to the PEAPSK RF transmission signal may be transmitted.

[0053] Finally, in the asynchronous preamplified amplitude phase shift demodulation and data clock recovery step (230), the signal output from the transmission step (220), i.e., the signal distorted according to bandwidth limitation and transmission path, can be asynchronously demodulated by generating positive pulse and negative pulse signals occurring in the phase change portion of the receiving side PEAPSK Baseband signal generated through the RF Mixer and Baseband BPF from the bandwidth-limited PEAPSK RF receiving signal through the receiving side BPF, thereby outputting the demodulated data RECOVERED pDATA signal and the recovered data clock RECOVERED pCLOCK through a Baseband binary phase shift demodulator (Baseband BPSK Demodulator); and generate the demodulated aDATA signal and the recovered aCLOCK signal from the receiving side PEAPSK Baseband signal through an asynchronous baseband amplitude shift demodulator (Baseband ASK Demodulator), and the RECOVERED pCLOCK signal or the recovered aCLOCK signal A RECOVERED aCLOCK signal can be output by synchronizing the restored aCLOCK signal with a signal delayed by a preset time, and a RECOVERED aDATA signal can be output by synchronizing the demodulated aDATA signal with the RECOVERED aCLOCK signal.

In addition, it provides a modulation and demodulation method that can be used for digital communication of devices requiring low power consumption and can be applied to mobile communication devices, and is suitable for implementing a System on Chip (SoC), thus offering high convenience and cost-effectiveness.
