Let $N_f$ denote the pulse rate in a multipath spread-spectrum system, and let the bit-error rate (BER) be the performance measure of the jointly or individually optimal multiuser…

Consider an uncoded multiuser system with a large number of users, and let $N_f$ denote its pulse rate and its system BER denote the bit-error rate of the multiuser detector. For t…

Let $N_f$ denote the pulse rate, let $P_e\mid N_f$ be the BER of the optimal multiuser detector (MUD) at pulse rate $N_f$, and let $\rho\mid N_f$ denote the correlation between the…

For spread-spectrum signalling aiming at narrow-band interference suppression, the relevant objects are the spreading operation and error-control coding used to transmit the signal…

Multiple-minimum-points conjecture. The proposed optimization leads to a problem with multiple and possibly identical minimum points.
