1. An apparatus for a communication system, comprising: a first and second correlator, each correlator including: a decover element for decovering a plurality of received samples to provide decovered half-symbols, wherein the decover element is configured to perform decovering with a decovering channelization symbol having a length (T) that is half the length (2T) of a covering channelization symbol used to cover the received samples; a switch for selectively outputting the decovered half-symbols corresponding to a first half of a symbol period along a first signal path and decovered half-symbols corresponding to a second half of the symbol period along a second signal path; first and second summers, respectively coupled to the first and second signal paths, for combining each pair of decovered half-symbols to provide a respective decovered symbol; and first and second multipliers for receiving the decovered symbols and pilot symbols to provide demodulated symbols.
