8 Introduction

for a subset of important samples from the data signal space whose

use is sufficient for a near optimum performance of the receiver. The

detail of implementation of the MCMC detector in hardware is also

presented and shown to be amenable to low-complexity logic and

parallelism.

Information transmitted over wireless networks can be accessed

by unauthorized users (eavesdroppers). Traditionally, ensuring that

only the legitimate receiver will be able to decipher the transmitted

information has been achieved by cryptographic approaches oper-
