Embodiment Construction

[0015] figure 1 is an exemplary block diagram showing a signal processing device according to an embodiment of the present invention. The signal processing device 100 is applicable to a communication device, such as a receiver in a communication system, for processing a received signal R(n). The signal processing device 100 may at least include a radio frequency interference canceller circuit 110 , a slicer 120 and a combiner 130 .

[0016] It is worth noting that, figure 1 It is a simplified schematic diagram of a signal processing device, in which only components related to the present invention are shown. Those skilled in the art can understand that a signal processing device, a receiver or a communication device should include other signal processing-related components for processing received signals. For example, a signal processing device, a receiver or a communication device should include one or more equalizer or filter circuits for compensating channel effects in a...

Abstract

A radio frequency interference estimation device is used for generating an estimated radio frequency interference signal and comprises a combiner, a first multiplier and a second multiplier. The combiner is configured to combine a first digital signal and a second digital signal to generate an estimated radio frequency interference signal. The first multiplier is used for generating a first digital signal according to the in-phase signal and a first cosine signal. The second multiplier is used for generating a second digital signal according to a quadrature phase signal and a first sinusoidal signal. The first sinusoidal signal and the first cosine signal are generated according to a frequency, and the in-phase signal and the quadrature-phase signal are generated according to the frequency and one or more harmonic components of the frequency.

Description

technical field [0001] The invention relates to a signal processing device used in a communication device, especially a signal processing device capable of effectively eliminating radio frequency interference. Background technique [0002] In most communication systems, external or internal interference may cause errors in transmitted signals, thereby limiting the performance of the communication system. For example, the noise in the transmission channel or the error of components in the communication device may cause the voltage level of the transmission signal to deviate from its ideal voltage level (ie, the voltage level set by the sending end). When the voltage level offset is too large, it will cause misjudgment at the receiving end and reduce communication performance. [0003] In view of this, communication devices are usually equipped with related circuits / devices to eliminate unwanted interference. The interference cancellation circuit / device usually adjusts / train...
