Abstract

Due to some drawbacks, such as the instability of the analog receiver in wideband conditions, an all-digital parallel receiver (APRX) has become more and more attractive. Based on the structure of an APRX proposed by the Jet Propulsion Laboratory (Gray, A. et al., JPL TDA Progress Report 42-131, NASA Code 314-30-11-20-06, 1997), a novel parallel algorithm for fractionally spaced equalization (PFSE) is proposed. Utilizing the constant modulus algorithm (CMA), PFSE takes best advantage of its data overlapping characteristic and achieves perfect combination with the APRX´s structure. Simulation results show that the performance of PFSE obviously predominates that of the T-spaced equalizer, with hardly any loss of performance compared with the corresponding serial FSE.
