Spread spectrum communication apparatus

摘要

A spread spectrum reception apparatus generates a local reference code and a timing signal having 1/2 the period of the reference code are generated. Correlation calculation between a received spread spectrum signal and the local reference code is performed. Upon reception of the correlation calculation result, a peak detector detects a correlation peak signal. The rate of a code generation clock is adjusted in accordance with the phase difference between the timing signal and the correlation peak signal to perform de-spread processing of the received signal.
