The BPSK modulation and demodulation algorithm is designed and implemented of software defined radio (SDR) transceiver system in this paper. The paper uses a Costas loop to achieve carrier synchronization when the BPSK demodulator is designed. And the loop realize the purpose of phase detection using the more accurate and fewer hardware resources occupy arc tangent phase detector. Firstly, the BPSK...
The frequency offset is the main problem of the conventional SDR receiver for demodulation. In order to overcome this drawback, the new methods are applied to improve the conventional Costas loop which is used to extract carrier. Firstly, the integration and accumulator is designed to realize the function of low-pass filter, which takes up fewer hardware resources. Secondly, the more accurate arctangent...
