more reliable communication.
Before we explore further the root cause of the poor performance of this detector,
we note that there ... gain, there is a law of diminishing marginal return: as L increases, the
marginal benefit decreases because of the law of large numbers, eventually converging
to the performance of the AWGN channel....
