In this letter, we study the effect of directional subscriber antennas on the reverse link performance of a power-controlled code-division multiple ac...

Four signal-to-noise ratio (SNR) estimators for quartenary phase-shift keying (QPSK)-like signaling are proposed and examined. Two are based on receiv...

This letter derives a bit-error-probability expression for an asynchronous multitone-code-division multiple access (CDMA) system and shows that the mu...

Based on stochastic calculus, we provide a rigorous formulation of the numerical evaluation of the error probabilities of two modulation techniques fo...

In this letter, we further analyze the security of the McEliece public-key cryptosystem according to the notions of public-key encryption security. We...
