Abstract
For burst communication systems, high estimation accuracy and large estimation range cannot be achieved at the same time at low signal to noise ratio(SNR), a hybrid data-aided(DA) and code-aided(CA) carrier synchronization scheme is proposed. Firstly, the synchronization parameters coarse estimation is performed based on maximization of periodogram and cross-correlation algorithm utilizing known pilot symbols. Secondly, the fine estimation is obtained based on expectationm aximization (EM) algorithm exploiting the pilot symbols and soft information from the extended Turbo decoder. On the basis, the cascade of periodogram maximization and multiple crosscorrelations has been proposed, which improves the estimation performance with low complexity. Simulation results show that the proposed algorithm can satisfy the requirements of frequency estimation range and accuracy, BER performance of Turbo decoding is very close to perfect synchronization and the estimation range can reach half of the symbol rate at a relatively efficient pilot cost.
