摘要： A transmission RF section (101) up-converts a DA-converted test signal into a high-frequency signal. An amplitude of the high-frequency signal, an envelope of which is detected by a loop-back section, is detected by an amplitude detector (400). An inverse characteristic calculator (402) converts the detected amplitude into an amplitude in the transmission RF section (101) using an inverse conversion table (407) and then calculates amplitude inverse characteristics. An FIR filter (103) corrects a signal band of a transmission signal based on a result of an inverse Fourier transform calculated by an IFFT section (405) based on the amplitude inverse characteristics as a variable factor.

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.

摘要： Provided are a time division receiver and a time division receiving method capable of mitigating leaks between branches for a time division multiplexed signal for which a plurality of branches have been time-division multiplexed even when processing using a single high-frequency circuit. In a time division receiver (100A), mixers (120-1 and 120-2) down-convert a time division multiplexed signal for which a plurality of branch signals have been time-division multiplexed. Time division separation units (130-1 and 130-2) separate the time division multiplexed signal which has been down-converted at the mixers (120-1 and 120-2) into branches, respectively. A residual charge initialization unit (160) initializes charges that are residual when a first branch signal passes for parasitic capacitances that occur in channels between the mixers (120-1 and 120-2) and the time division separation units (130-1 and 130-2) to the residual charges before passing of a second branch signal.
