Improved Closed-Form Bounds On The Performance Of Convolutional Codes With Correlated Rayleigh Fading, Dwight Hutchenson
Improved Closed-Form Bounds On The Performance Of Convolutional Codes With Correlated Rayleigh Fading, Dwight Hutchenson
All Theses
New bounds on the probability of bit error are presented for a coded communication system with binary antipodal modulation and soft-decision maximum-likelihood decoding over a correlated Rayleigh-fading channel. The bounds are closed-form expressions in terms of the code's transfer function; they are illustrated by considering a system using convolutional encoding. A long-standing conjecture regarding the worst-case error event in correlated Rician fading is proven for the special case of correlated Rayleigh fading, and it is used in the development of some of the new bounds. The bounds are shown to be tighter than previously developed closed-form bounds for communications using …

A Capacity-Approaching Coded Modulation Scheme For Non-Coherent Fading Channels, Youngjeon Cho
LSU Master's Theses
Approaching the Shannon limit of the communication channels has been studied by many researchers to efficiently and reliably transmit data through the channels. To solve this problem, various methods and schemes have been proposed for approaching the theoretical limit for Shannon’s channel capacity. Among them, both low-density parity check (LDPC) codes and Turbo codes have been proposed to minimize the bit error rate (BER). Therefore, understanding of LDPC codes and Turbo codes is useful for their applications in modern communication systems. The study about non-coherent channels, which do not require explicit knowledge or estimation of the channel state information, has …
