Abstract:
1. A method of determining a transmitted symbol from among a plurality of possible transmitted symbols, the method comprising: receiving a signal representing one of the possible transmitted symbols; successively eliminating as the determined transmitted symbol at least one of the plurality of possible transmitted symbols by sequentially applying to the received signal a plurality of decision rules that maximize network throughput by minimizing a sum of weighted costs of making a decision based on a magnitude of the received signal, the cost of making a decision being associated with the effect on overall throughput performance due to choosing a particular symbol as the most likely transmitted symbol when the same or a different symbol was actually transmitted, wherein in the sum, each cost is weighted by an a priori probability that a particular symbol was actually sent multiplied by an a posteriori conditional probability of a decision made on the received signal based on its received magnitude.
