method and apparatus for digital communications with metric fuzzy decision-making

摘要

a decoding device (200) decodes a signal modulated with a modulation phase shift at multiple levels with differential coding (depsk).a coherent receiver (101) receives and then emits out the modulated signal with modulation depsk consistent for applying a metric calculator (201).the metric computer (201) generates a soft decision metric. (? (n) corresponding to the modulated signal with a modulation depsk consistent that is emitted out and applied to a decodificathours (107) for correction of the error of forwarding (ec).the decoder of the ec (107) decodes the modulated signal with a modulation depsk consistent in accordance with the metric making soft? (? (n) corresponding to the modulated signal with modulazionand depsk consistent.
