Abstract :
A detection error mechanism termed delay ambiguity is identified as one of the main causes of the irreducible bit error rate observed for data detection over fast fading communication channels. A periodic sequence of phase rotations applied to the phase shift keyed (PSK) transmit data symbols is proposed to prevent this type of detection error
