WIRELESS COMMUNICATION STATION

摘要

A wireless communication apparatus is provided to reduce the mutual interference by reducing the consumed transmission power, and improving a communication-available bit rate by adaptively using the increased channel capacity. A wireless frequency circuit(101) converts the signals received in an antenna into baseband signals. A demodulator(102) demodulates the baseband signals. A channel decoder(121) performs error correction every encoding unit, a reception quality decision device(140) receives the error-corrected result, and an error detection unit(115) detects errors and prepares receipt quality information for showing whether errors exist or not. A power signal generator(105) receives the baseband signals and generates a transmission power control signal according to a power control algorithm. A multiplexer(109) multiplexes the receipt quality information, the transmission power control signal, the third pilot signal generated in the third pilot signal generator(130) and data signals which are obtained and received through the channel coding by an error correction coder(106) and an interleaver(107). A modulator(110) modulates the multiplexed signals, and the wireless frequency circuit transmits the modulated signals in radiowave type.
