A codeword synthesizing system and a correlation system for use with a spread spectrum communications system. In one embodiment, the codeword synthesizing system typically associated with a transmitter includes a base sequence generating subsystem, a modifier sequence generating subsystem and a concatenating subsystem. The base sequence generating subsystem is configured to create base sequences having a length less than a synthesized codeword. The modifier sequence generating subsystem is configured to create a modifier sequence, and the concatenating subsystem is configured to produce the synthesized codeword by multiplying each of the base sequences by an element of the modifier sequence. In one embodiment, the correlation system typically associated with a receiver includes a partial correlating subsystem, a memory subsystem and a combining subsystem. The partial correlating subsystem correlates base sequences of a synthesized codeword to a template and derives multiple partially correlated resultants. The memory subsystem temporarily stores the partially correlated resultants, and the combining subsystem sums weighted values of the partially correlated resultants to provide a correlated value of the synthesized codeword.
