Capacity analysis for channels with side information at the receiver has been an active area of interest. This problem is well investigated for the case of finite alphabet channels. However, the results are not easily generalizable to the case of con

A sphere packing lower bound and a pairwise error upper bound are derived on error probability of space-time-frequency coded OFDM systems over multiple antenna block-fading channels. These bounds are useful in performance analysis and design of the c

In this paper, we consider the problem of space-time coding over Rician channels in the presence of spatio-temporal correlation. We derive an upper bound on the pairwise word error probability (PWEP) of space-time codes and use it as a basis for a un

A sphere-packing bound (SPB) on average word-error probability (WEP) is derived to determine the performance limits of space-time codes on Rayleigh block-fading channels under delay and maximum energy constraints. Two other explicit bounds, a looser

We present a decision-making framework for the problem of echo control. This framework enables a unified approach to detecting the changes in the echo path, adaptation, and double-talk detection. Using this framework, we provide new analytical result

We prove the uniqueness of the capacity-achieving input distribution for a noncoherent flat-fading channel (Rayleigh or Rician), subject to a second moment constraint. For this purpose, we first show the uniqueness and symmetry of the capacity-achiev

We present a sphere packing bound (SPB) approach to investigate the performance limits of Rayleigh block-fading, multiple antenna systems. Specifically, we derive three sphere packing lower bounds, one tight, one loose, and one approximate, on averag

In this part, we consider the capacity analysis for wireless mobile systems with multiple antenna architectures. We apply the results of the first part to a commonly known baseband, discrete-time multiple antenna system where both the transmitter and

We study the impact of spatio-temporal correlation on the performance of space-time codes. We present an upper bound on pairwise word error probability of space-time codes over flat-fading Rician channels. The bound, which has a closed form expressio
