Abstract

The complete structure of a fully digital all feed forward synchronization unit is presented, establishing clock and carrier synchronization. Although the basic synchronization concept is able to operate solely on random data, a structure is presented which is tailored to spontaneous packet transmission and time division multiple access (TDMA) applications, where additional frame synchronization has to be performed. It is shown that frame and frequency synchronization can be efficiently combined. The key features of the scheme, which are presented in terms of estimation error variances and bit error rate (BER), ensure high speed synchronization with negligible decoder performance degradation.
