ABSTRACT:
An over-sampling circuit is provided at a front stage of a digital matched filter, and a received signal is over-sampled with it. Synchronous acquisition of the received spread spectrum signal is implemented by adding the data obtained by the over-sampling, inputting it into the digital matched filter, and then performing a correlation thereon.
