Abstract
A receiver includes a channel-matched-filter for outputting a Rake-combining result from a digital spread spectrum signal; a carrier recovery circuit which removes an offset of a carrier wave from the combining result; a correlation circuit which detects correlation; a symbol timing detection circuit which extracts a symbol from the correlation; a symbol determination circuit which regenerates data from the symbol; a framer circuit which discriminates a frame configuration; and a symbol timing recovery circuit which generates a timing phase for each of symbol timings. The channel-matched-filter performs multi-phasing compensation and, in accordance with a timing phase from the symbol timing recovery circuit, performs synchronization tracking.
