ABSTRACT:
An automatically gain-controlled analog received signal is AD converted to a digital signal, which is subjected to quadrature demodulation processing through operation. The quadrature demodulation result is subjected to low-pass filter processing through operation, that is, a digital detection is performed by software processing to a variable in each software processing in accordance with changes in the modulation method of the received signal and in the symbol transmission rate.
