Research on implementation of OFDM burst packet transmission on software radio platform of FPGA

Fast verification of the prototype design on software radio platform has become one of the most important research topics in communication systems. Based on OFDM receiver which is implemented on FPGA, the paper focuses on many key issues in the implementation of the strategy in software wireless platform such as OFDM frame synchronization, frequency compensation, symbol timing, etc. The proposed corresponding optimizations of these algorithms significantly reduced the usage of hardware resources while ensuring the receiver´s highest frequency as 50 MHz. According to the theoretical analysis and the test result on the platform, the receiver can achieve 0 PER (packet error ratio) at 30 MHz IF after the modification and optimization of the algorithms.
