摘要： A diversity receiver respectively receiving signals in two branches includes two demodulating sections for producing respective amplitude and phases of received signals at a unit of symbol. The receiver includes a memory access section for producing an amplitude ratio of the amplitude of the received signals and a phase difference between the phases of the received signals. The receiver further includes a storage section for storing at least one relative phase difference between a phase of a vector-combined signal combined based on the received signals and one of the phases of the received signals for an address given by the amplitude ratio and the phase difference of the received signals. The phase of the vector-combined signal is previously calculated based on the amplitude ratio, the phase difference, and the one of the phases of the received signals. The receiver further includes an adding section for adding the relative phase difference produced from the storage section being addressed by the amplitude ratio and the phase difference produced from the memory access section to the one of the phases of the received signals to produce the phase of the vector-combined signal combined based on the received signals.

摘要： In a wireless transmitting/receiving device of TDD system etc., a transmission signal is detected on the transmitting side in a specified transmission period, a signal reflected from an antenna through a circulator is detected on the receiving side in the transmission period and a reception signal is detected on the receiving side in a specified reception period. In this case, in a part of the transmission period a transmission signal having been detected on the transmitting side is selected while in the remaining part of the transmission period a reflection signal having been detected on the receiving side through a circulator from an antenna is selected, and in the reception period a reception signal having been detected on the receiving side through the circulator from the antenna is selected and outputted.
