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…

Consider two polar codes $A$ and $B$ with the same code length $n$ and message length $k$. Let ${\rm FER_{SC}}(\cdot)$ and ${\rm FER_{ML}}(\cdot)$ denote their frame-error rates un…
