ABSTRACT:
In a wireless communication system having a receiver which receives, through plural reception antennae, signals transmitted from plural transmission antennae, bit likelihood can be surely calculated without requiring a selection processing. A transmitter has M transmission antennae, and transmits signals through the transmission antennae, respectively. A receiver has N reception antennae, and receives signals. K nulling devices perform nulling with use of signals received, and output part of nulling signals. K demodulation devices are inputted with nulling signals, demodulate signals, and output demodulated signals. A parallel-serial conversion device is inputted with demodulated signals, converts the parallel format thereof into a serial format, and outputs the result as demodulated data.
