| Abstract | In this work a joint clock recovery (CR) and equalization scheme for short burst transmissions is presented. The joint optimization performance may be pursued by means of both data aided and decision directed solutions. The novel algorithm is based on an iterative scheme, exploiting a timing error function sampled at symbol rate. The symbol timing adjustment is implemented by an interpolation filter, built according to the Farrow structure. Equalization is obtained by baud spaced zero forcing (ZF) and minimum mean square error (MMSE) linear filtering. Performance is evaluated by simulating a QPSK transceiver and simulations results are compared with the ideal solutions, for both symbol timing recovery and channel equalization, under frequency selective multipath fading channel conditions. |
