Abstract
Description
Technical Field
[0001] This invention relates to the field of wireless electronic equipment, and more specifically, to an electromagnetic holographic computing and sensing type wireless electronic equipment and its operating method. Background Technology
[0002] Co-channel interference is a core problem facing current wireless electronic equipment. When multiple electronic devices operate collaboratively in the same space, to avoid mutual interference on the same frequency, orthogonal co-location methods such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), and Space Division Multiple Access (SDMA) have been invented. The core idea is to allocate non-overlapping "dedicated channels" for users in the time, frequency, or spatial dimensions, thus avoiding co-channel conflicts at the source. TDMA uses the same frequency band in a time-division manner, FDMA allocates independent sub-bands, and SDMA uses beamforming to isolate signals in different spatial directions.
[0003] However, in actual use, although the TDMA, FDMA, and SDMA working mechanisms can avoid the problem of co-channel interference between multiple wireless electronic devices to a certain extent, when there is intentional or unintentional interference, these interferences do not work according to the pre-planned TDMA, FDMA, and SDMA mechanisms, but overlap with those originally planned non-overlapping "dedicated channels", and then the wireless electronic devices will not be able to work properly.
[0004] To combat interference, various anti-interference techniques have been invented, such as frequency hopping (FH), spread spectrum (DS), and adaptive interference suppression. While these techniques can combat interference to some extent, their capabilities are usually limited. For example, frequency hopping and spread spectrum anti-interference techniques can effectively combat interference of about 10-15 dB; phased array adaptive interference suppression can effectively combat sidelobe interference of about 40 dB, but cannot combat interference in the main lobe direction.
[0005] Based on orthogonal co-location technologies such as TDMA, FDMA, and SDMA, and anti-interference technologies such as frequency hopping, spread spectrum, and adaptive interference suppression, modern wireless electronic equipment has formed a fixed hardware architecture design pattern. This involves designing electronic circuits in three dimensions—time, frequency, and space—to construct "dedicated channels" to ensure the normal operation of the wireless electronic equipment. For example, TDMA cooperative operation is constructed by dividing transmit and receive time slots into control circuits; FDMA cooperative operation is constructed by tuning the radio frequency channel to an independent frequency sub-band; SDMA cooperative operation is constructed by using phased array technology and beamforming to isolate signals in different spatial directions; frequency hopping anti-interference operation is constructed by using high-speed frequency synthesizers; spread spectrum anti-interference operation is constructed by using spread spectrum and despreading circuits; and adaptive sidelobe suppression anti-interference operation is constructed by using adaptive beamforming technology.
[0006] Currently, wireless electronic equipment designed based on the three dimensions of time, frequency, and space essentially sacrifices the dynamic sharing of resources for orthogonality. When this dynamic sharing is intentionally or unintentionally disrupted, the wireless electronic equipment will be unable to function effectively. The root cause of this situation is that current understanding of wireless electronic equipment is limited to these three dimensions. This limitation in understanding leads people to believe that co-channel interference is a natural phenomenon and can only be solved through orthogonal co-location technologies such as TDMA, FDMA, and SDMA to address the problem of coordinated co-location among multiple wireless electronic devices. Therefore, the following limitations have been implicitly accepted in the design of wireless electronic equipment based on the three dimensions of time, frequency, and space: 1. Co-channel interference is inherent; for example, "if interference is introduced in a conference room, mobile phones should inherently be unable to function properly." 2. To avoid co-channel interference, spectrum resources are extremely scarce. Summary of the Invention
[0007] To address the limitations of current wireless electronic equipment, this invention provides an electromagnetic holographic computing and sensing type wireless electronic equipment and its operating method.
[0008] The present invention provides an electromagnetic holographic computing and sensing wireless electronic equipment, comprising N receiving antennas, N receiving channels, N analog-to-digital conversion units, 1 electromagnetic holographic computing and sensing unit, 1 target matching and recognition unit, 1 signal processing unit, 1 digital-to-analog conversion unit, 1 transmission channel, and 1 transmission antenna; The N receiving antennas are sequentially connected to one electromagnetic holographic computing and sensing unit via N receiving channels and N analog-to-digital conversion units; The electromagnetic holographic computing and sensing unit is connected to a transmitting antenna via a target matching and recognition unit, a signal processing unit, a digital-to-analog conversion unit, and a transmitting channel.
[0009] In some preferred embodiments, for a full-duplex system, one transmitting antenna and N receiving antennas are completely independent; for a half-duplex system, one transmitting antenna and one of the N receiving antennas share the same antenna via a duplexer.
[0010] This invention also provides a method for operating the above-mentioned electromagnetic holographic computational sensing wireless electronic equipment, including: S1, use N receiving antennas to receive S unknown electromagnetic wave radiation sources in space within the current wireless electronic equipment tuning frequency range, requiring N>S; S2, N receiving channels filter, amplify and frequency convert the radio frequency signals received by N receiving antennas respectively to form N intermediate frequency or complex baseband analog signals; S3, N analog-to-digital conversion units perform analog-to-digital conversion on the N analog signals sent from the N receiving channels, converting them into N digital signals, which are then input into the electromagnetic holographic sensing and computing unit; S4, the electromagnetic holographic computing and sensing unit performs holographic electromagnetic sensing and calculation on the input N digital signals, calculates the waveforms of S unknown electromagnetic radiation sources in the space within the current wireless electronic equipment tuning frequency range, and inputs them into the target matching and identification unit; S5, the target matching and recognition unit matches and recognizes the waveforms of the S unknown electromagnetic radiation sources based on prior information, selects the target signal from the S unknown electromagnetic radiation sources, and inputs it into the signal processing unit. S6, the signal processing unit performs signal processing on the target signal identified by the matching, obtains the received information and outputs it; S7, the signal processing unit receives the external information stream to be transmitted, the digital-to-analog conversion unit performs digital-to-analog conversion on the external information stream to be transmitted and then inputs it into the transmission channel for frequency conversion, filtering and amplification, and sends the processed signal to the transmission antenna for transmission.
[0011] In some preferred embodiments, step S4 involves performing holographic electromagnetic sensing calculations, including: For input electromagnetic holographic sensing computing unit Digital signal, from any one data signal Y Extract two consecutive segments of length from the middle. The data segments are used to construct a data matrix, denoted as follows: , ,have ,in To represent the field of complex numbers, it is required that... ; For each digital signal, by calculation The waveforms of all S unknown electromagnetic radiation sources within the current tuning frequency range of wireless electronic equipment are obtained; among them This indicates the calculation of the matrix inverse. This indicates the calculation of the eigenvalues of a matrix. This indicates the computation of the pseudo-inverse of a matrix.
[0012] In some preferred embodiments, step S5 involves matching and identifying the waveforms of the S unknown electromagnetic radiation sources based on prior information, including: Pre-set prior information according to system type; Based on prior information, the waveforms of the S unknown electromagnetic radiation sources are matched and identified through correlation matching, and the target signal is selected from the S unknown electromagnetic radiation sources.
[0013] In some preferred embodiments, the step of presetting prior information according to system type includes: For a communication system, the prior information is a pre-defined frame pilot symbol; For radar systems, the prior information is a pre-set pulse compression waveform signal.
[0014] In some preferred embodiments, the relevant matching can be performed serially or in parallel.
[0015] In summary, this invention provides an electromagnetic holographic computational sensing wireless electronic device based on high-dimensional algebraic geometric spatial cognition, which has the following beneficial effects: 1. Co-channel interference is no longer effective, and spectrum resources are released. The wireless electronic equipment of this invention no longer needs to divide "dedicated channels" in the three dimensions of time, space, and frequency. Instead, it senses the signals of all radiation sources in space (within the tuning frequency range of the wireless electronic equipment channel) through holographic calculation, regardless of whether these radiation sources are on the same frequency or have overlapping frequencies. Since all radiation sources in space can be directly calculated, mutual interference between radiation sources on the same frequency no longer exists. And when the wireless electronic equipment can operate freely at the same frequency, spectrum resources are released.
[0016] 2. The performance of wireless electronic equipment will be qualitatively improved. Current wireless electronic equipment requires dedicated channels across time, space, and frequency dimensions, working collaboratively using mechanisms such as TDMA, FDMA, and SDMA. When intentional or unintentional interference exists, it cannot function effectively, as seen in civilian 4G and 5G. To combat interference, spectrum resources need to be expanded (e.g., FH, DS), and a large number of redundant information bits need to be added to correct and recover information from the interfered dedicated channels. Taking FH anti-interference communication as an example, it typically requires expanding spectrum resources by 100 times and sacrificing more than 10 times the effective information transmission bandwidth to achieve an effective anti-interference capability of 10dB~20dB. The electromagnetic holographic computational sensing wireless electronic equipment of this invention does not require extended spectrum resources or the addition of a large number of redundant information bits. It directly calculates all radiation source signals in space, including high-power strong interference signals and useful weak signals. Therefore, it can achieve strong anti-interference capabilities without occupying extra spectrum resources. Its comprehensive performance indicators can reach 1000 to 10000 times that of current electronic equipment, achieving a qualitative improvement. Taking phased array radar as an example, beamforming technology forms a main lobe in the airspace, and adaptive interference suppression and other technologies can effectively suppress interference from side lobes, but cannot suppress interference from the main lobe. The electromagnetic holographic computational sensing wireless electronic equipment, however, does not need to form a main lobe; it directly performs holographic sensing and computation of all radiation sources in space. Therefore, it can effectively suppress both side lobe interference and main lobe interference. Attached Figure Description

[0020] Addressing the limitations of current wireless electronic equipment, recent advancements in computing power and artificial intelligence have broadened the understanding of this technology beyond the three dimensions of time, space, and frequency. The understanding now extends to a higher-dimensional abstract algebraic geometric space. This higher dimension allows for the holographic perception and calculation of every electromagnetic wave radiating through the air, eliminating the need for the electronic circuitry of current wireless electronic equipment that divides channels into non-overlapping sections. Therefore, this invention provides an electromagnetic holographic computing and sensing wireless electronic equipment based on high-dimensional algebraic geometric space cognition.

This indicates the calculation of the eigenvalues of a matrix. This indicates the computation of the pseudo-inverse of a matrix.
[0026] S5, the target matching and recognition unit matches and recognizes the waveforms of the S unknown electromagnetic radiation sources based on prior information, selects the target signal of interest from the S unknown electromagnetic radiation sources, and inputs it into the signal processing unit.
[0027] In this embodiment of the invention, the step of matching and identifying the waveforms of the S unknown electromagnetic radiation sources based on prior information includes: Prior information is preset according to the system type; preferably, for a communication system, the prior information is a preset frame pilot symbol; for a radar system, the prior information is a preset pulse compression waveform signal. Based on prior information, the waveforms of S unknown electromagnetic radiation sources are matched and identified through correlation matching, and the target signal is selected from the S unknown electromagnetic radiation sources. The correlation matching can be performed serially or in parallel. Through correlation matching, the waveform of interest is identified and extracted as the target signal, while other waveforms of no interest are ignored.
[0028] S6, the signal processing unit performs signal processing on the matched and identified target signal to obtain the received information and output it to the system user.
