简介
This paper proposes a synchronization method for implementation of an OFDM system based on the TMS320C6416 DSP. The method is to meet the constraints of signal processing in real time conditions, and ensure the Quality of Services regarding the received signal quality. It is proven that the complexity of the proposed method is significantly reduced in comparison with the conventional one, and thus, the time constraint for synchronization is fulfilled. Moreover, the starting point of each OFDM frame stored in the receiver DSP buffers can be precisely detected. The data rate obtained by applying the Ping-Pong Buffer technique is significantly enhanced. Measurement results are compared with the theoretical results to validate our proposed mechanisms. Files and audio transfer are tested to demonstrate the performance of the implemented system.
