摘要： Disclosed are a distortion-correcting receiver and a distortion correction method capable of precisely cancelling inter-modulation secondary distortion even when an input signal is markedly band-limited in a reception processing unit. In the distortion-correcting receiver (100), the reception processing unit (110) executes reception processing of the input signal and outputs a received signal. A replica signal generation unit (120) generates a replica signal of the inter-modulation distortion component of the input signal by use of the input signal. A correction signal generation unit (130) comprises a frequency property imparting unit (131) and a weighting unit (132), adjusts the frequency property and the gain of the replica signal, and generates a correction signal. A correction signal injection unit (140) adds the reverse-phase signal of the correction signal to the received signal to correct the received signal.

摘要： Disclosed are a nonlinear distortion compensating receiver and nonlinear distortion compensation method, wherein nonlinear distortion is reduced with a simple circuit configuration. A correction (opposite characteristics) filter (104) has characteristics opposite that of the frequency characteristics of a direct sampling mixer (102) and corrects signals sampled by the direct sampling mixer (102). In the main path, a LPF (106) extracts a frequency band component of a desired signal from the corrected signal. In the replica path, a BPF (107) extracts the frequency band component of a blocker signal from the corrected signal. A cubing circuit (108) uses the frequency band component of the blocker signal to generate a replica signal for the nonlinear distortion. An adaptive filter (110) performs filter processing on the replica signal while updating the filter coefficients. A subtractor (111) subtracts the output signal of the adaptive filter (110) from the frequency band component of the extracted desired signal and outputs the subtraction result as the desired signal.

摘要： A WiGig wireless device partially performs a masking processing on a preamble of a transmission signal frame and generates a repetition pattern of the same pulse capable of being used in a correlation detection of a sensor. That is, a repetition pattern of a Golay code is output by intermittently performing the masking processing on the Golay code sequence. The sensor performs the correlation detection using a pulse compression technology, thereby detecting the antenna radiation pattern even in an environment where a reflected wave is generated, by separating the direct wave and the reflected wave.

摘要： A ΔΣADC is provided that is capable of suppressing increase of a circuit scale without losing noise shaping function even when a switching speed of a switch for performing time-division process is lower than a sampling rate of the ΔΣADC. For a code values provided by a comparator (105), the ΔΣADC (100) has a first storage section (106-1) and a second storage section (106-2) respectively for signal sequences (a first signal sequence and a second signal sequence) constituting a time-divisionally combined signal. Then, one of the two storage sections (i.e. the first storage section (106-1) and the second storage section (106-2)) that corresponds to a branch selection signal is configured to store the code value obtained from the comparator (105). On the other hand, one of the two storage sections (i.e. the first storage section (106-1) and the second storage section (106-2)) that is not the storage section corresponding to the branch selection signal is configured to hold the already stored code value.
