Code-division multiplexing (CDM) is a robust transmission scheme recently adopted for satellite multimedia broadcasting systems. A drawback of CDM is its high peak-to-average power ratio, which can be reduced by clipping the baseband CDM signal. However, clipping introduces in-band noise that may considerably degrade system performance. Proposed is an iterative decision-directed technique for detecting clipped CDM signals. The performance of the algorithm is studied by means of computer simulation. Simulation results show that the proposed technique can provide significant performance improvement compared to a conventional (linear) detection of clipped CDM signals.
