Abstract

A new method for baseband demodulation of OQPSK has been proposed in this paper. The sampling rate is two times the Nyquist rate which is very low compared with similar Demodulators. The demodulation process includes baseband mixer bank, Matching filter, Timing recovery and Phase recovery. To fasten the process, we have used the fast convolution in Matching filter. Besides, a new Phase recovery method has been proposed which can be used in other phase Demodulators such as QPSK. The High data rate Demodulator will demodulate OQPSK with data rates ranging from 1 Mega-bits to more than 500 Mega-bits per second. The experiments show that this architecture can efficiently work with performance loss less than 0. 8dB for low SNR (i. e. Eb/N0≃ 5dB) and 0. 2 dB for high SNR (i. e. Eb/N0≃ 10dB).
