Abstract
An apparatus for and method of deciding symbols in a M-ary phase shift keying (MPSK) system are provided. The apparatus includes: a linear transform unit performing linear transform, to which a phase error is applied, of a received pair of symbols; and a symbol decision unit deciding a transmitted symbol corresponding to the received pair of symbols according to the sign value of the transformed symbol pair. According to the apparatus and method, degradation of a symbol error rate caused by a phase error when an MPSK signal is demodulated can be improved and a phase error can be estimated through a simple method.
