Channels leading to rapid error recovery for decision feedback equalizers: Passivity analysis

Abstract

The authors define the finite-error-recovery-time problem. The background passivity theory is then given along with the authors' main theorem. Four applications are presented, including an analysis of a real channel. Convergence rates and explicit bounds are established, given an exponential overbound on the channel impulse response. The result for M-ary data is presented, and the error-recovery-time bound is related to back to the binary case. For high SNR channels satisfying a passivity constraint, a formula for error probability is given. Show more
