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 paper presents hardware efficient design of digital signal processing (DSP) based bit synchronizer and lock detector circuit for bi-phase data. The system is developed for one of the payload of Chandrayaan-I mission, and tested for its performance. Apart from the implementation, paper describes the mathematical modeling of bit synchronizer. The whole design is accommodated in a single Actel-1280...
