Low complexity synchronization in TD-SCDMA systems

At present, wireless communication technology is rapidly evolving to the 4G technology. Based on the physical frame structure of TD-LTE technology being same to TD-SCDMA, we propose a low complexity method of TD-SCDMA downlink synchronization detection and the performance of TD-SCDMA downlink synchronization, with different quantization word length and SNR, is designed and tested by using software simulation. Furthermore, the required minimized word length is found. We verify our algorithm by computer simulations, and the results show a good performance in a wide range of signal-to-noise ratios (SNRs).
