TY - JOUR ID - 623079 L3 - citeulike-article-id:3089306 N2 - In this paper, we derive error probability expressions for binary phase-shift keying (BPSK) and quaternary phase-shift keying (QPSK) spread direct-sequence spread-spectrum (DSSS) systems employing random spreading sequences with RAKE receivers.
