New method for computation of error probability in PSK systems with interference

A very efficient technique for the computation of error probability in ASK systems with M = 2 m (m an integer) symbols or QASK systems with M2 symblos in the presence of intersymbols interference was presented by Jenq, Liu and Thomas, and this technique was extended by Jenq to coherent PSK (no phase jitter) with M = 2, 4 and 8 symbols. In the present paper we extend this technique to PSK (phase jitter or misalingnment is possible) with 8 and 16 symbols by deriving lower and upper bounds which are close to each other.
