Abstract

We introduce a reliable I/Q regeneration algorithm for digital video broadcasting system (DVB-S) using a 5-port junction direct conversion receiver. The DVB-S uses two modulation schemes; QPSK and 8PSK. We propose two cost functions for each modulation scheme. The proposed algorithm utilizes the characteristic of the modulated symbol, so it simplifies the phase-offset compensation problem with low complexity. Simulation results show that bit error rate (BER) of the proposed scheme agrees very well with the theoretical BER for QPSK and 8PSK
