APPARATUS AND METHOD FOR RECEIVING SIGNAL IN COMMUNICATION SYSTEM USING GAUSSIAN FREQUENCY SHIFT KEYING MODULATION SCHEME

摘要

The present invention provides a signal reception method of a signal reception device in a communication system supporting a Gaussian frequency shift keying (GFSK) modulation scheme, a process of receiving a signal, and a GFSK modulation scheme and a maximum for the received signal. It includes a process of estimating a codeword vector by performing a signal detection operation based on a GFSK-MLSE scheme based on a maximum likelihood sequence estimation (MLSE) scheme. In addition, the GFSK-MLSE scheme is characterized by estimating and compensating for a frequency offset, a modulation index offset, and a reference phase error.
