Comparison of three suboptimum detection procedures

Three suboptimum detection procedures previously introduced in the literature are here compared from the point of view of immunity to additive Gaussian noise. On the basis of this comparison, an approximate expression for the probability of error versus signal/noise power ratio is derived for the detection procedure based on the weighting of partial decisions.

Suboptimum detection procedure based on the weighting of partial decisions

Commercially available m.o.s. microprocessors are relatively slow and unsuitable for the implementation of medium-speed voice-band data modems. The main problem is algebraic multiplication of the optimum detection algorithm. A suboptimal detection procedure without multiplication is presented and is suitable for m.o.s. microprocessor-based implementation.
