Method for demodulating signals of a multi-access system that may collide and device for implementing same

摘要

The method involves measuring a phase of a global signal common to two mutually collided time-multiplexed signals (S1, S2). An expected value of the global signal phase is estimated depending on a pair of phase states of the two signals and for each scenario of a received pair of bits of the two signals. A metric associated with the scenario is calculated. A bit-stream pair of each of the signals offering smallest aggregate metric is conserved, where an aggregate metric is a sum of an aggregate metric calculated in preceding iteration and the metric calculated with the scenario. An independent claim is also included for an equipment for demodulating two mutually collided signals.
