The Optimal BPSK Demodulator with a l-bit A/D Front-end
نویسنده
چکیده
In this paper an unconventional, simple BPSK demodulator is proposed. Complexity of the conventional BPSK demodulator is reduced by utilizing a l-bit Analog-to-Digital (A/D) converter front-end. The optimal detection rule is derived for BPSK signals going through the l-bit A/D front-end. The key element of the optimal demodulation process is a pair of weighting factors that act as phase references. A simple algorithm for estimating the weighting factors is proposed and shown to be effective. Simulations are performed and the results are compared with the conventional BPSK demodulator.

متن کاملAn Improved Bpsk Demodulator for the 1.2mbit/s Packet-radio Rtx ===============================================================
Efficient data transmission requires efficient modulation and demodulation techniques, both for terrestrial radio links and for satellite communications. Unfortunately, most amateur transmissions still use rather inefficient FSK modulation. Although an incoherent FM transceiver may look simpler than a coherent PSK transceiver, the practical implementation of either design is equally demanding. ...
