Patent ID: 7412020

Claim:
A method of communications comprising: determining the cutoff rate of a communication channel by analyzing an arbitrary channel correlation and a training and estimation scheme wherein the cutoff rate (R O ) is determined from equation (14); R o = - 1 T ⁢ ∑ l = 1 T - 1 ⁢ ⁢ log 2 ⁡ [ 1 M ⁢ ∑ m = 0 M - 1 ⁢ ⁢ 1 + K D ⁡ ( 1 - ω l ) 1 + K D ⁡ ( 1 - ω l ⁢ cos 2 ⁡ ( π ⁢ ⁢ m M ) ) ] wherein the estimation scheme is adjusted by applying the analysis of causal and noncausal estimators to the model of the communication channel; and allocating resources for the communication channel corresponding to maximization of the cutoff rate.
