Abstract


GFSK modulation is an wireless communication standard for the purpose of Automatic Meter Reading (AMR) in smart grid. This paper presents the implementation of GFSK digital receiver based on CORDIC algorithm. The receiver is made up of the frequency offset estimation, frequency compensation, bit synchronization and demodulation modules. The digital receiver is equipped with two identical baseband signal processing branches, in which a large carrier frequency offset can be accommodated.
