Abstract

In personal communication systems the burst mode data transmission being more widely used, like in digital cellular phone, cellular digital packet data, Mobitex, and DECT. An ultra fast synchronized symbol timing recovery approach is presented. It is based on the balanced threshold zero crossing differential phase evaluation of the input baseband signal, and instantly locks the phase of a numerical controlled oscillator. This symbol timing recovery is implemented by a digital circuit. Measurement shows that in the burst mode data transmission, within 3 bits it can extract the timing clock from the input signal, with very little degradation in BER performance and jitter acquaintance
