Joint Symbol Timing Recovery and Equalization for Short Burst Transmissions

This paper presents a joint symbol timing recovery and equalization scheme for short burst transmission formats, useful in modern wireless systems, like, for instance, time- division multiple access schemes and future wireless packet data networks. Both data aided and decision directed solutions are considered and the joint optimization performance is pursued by means of an iterative scheme which exploits a timing error function sampled at symbol rate, implemented by means of the Farrow structure for the interpolation filter. Equalization is obtained by zero forcing linear filtering, considering a baud spaced implementation. Performance is evaluated by simulating QPSK transceivers and simulations results are compared with the ideal solutions for both symbol timing recovery and zero forcing channel equalization under frequency selective multipath fading.
