On symbol timing recovery in all-digital receivers

Research output: Contribution to journalConference article

Abstract

Interpolating the original sampled sequence achieves timing synchronization in a digital receiver to produce another sampled sequence synchronized to the symbol rate or a multiple of the symbol rate. A Gardner's adaptive sampling conversion algorithm that performs this function is applied to the binary phase shift keying (BPSK) and 4-ary PAM. The simulation of the two schemes, in the presence of additive white Gaussian noise and intersymbol interference along with Gardner's algorithm and a fractionally spaced equalizer, showed that the algorithm gives good bit error rate performance for BPSK in all situations and at different sampling frequencies, but poor performance for the 4-ary PAM scheme.
