16QAM调制与解调程序，使用matlab运行(16QAM modulation and demodulation process, the use of matlab run)

在AWGN信号下，实现pi-4 QPSK调制解调(pi-4 QPSK modulation and demodulation)

该程序实现了跳时UWB技术的调制与解调，对于UWB系统的设计具有一定参考价值(this program realize TH UWB with modulation and demodulation module.it has significant value for UWB system design.)

LDPC Codes – a brief Tutorial Bernhard M.J. Leiner, Stud.ID.: 53418L bleiner@gmail.com April 8, 2005

In this paper, we present a Selected Mapping (SLM) PAPR reduction technique for MIMOOFDM system with special protection of Side Information (SI). Selected Mapping (SLM) is a powerful PAPR reduction technique since it does not cause any signal distortion and simple to implement. As a special protection for the Side Information (SI) of SLM technique, we propose a SI power allocation procedure. Simulation results show that our proposed technique gives significantly better BER performance than the ordinary SLM technique for MIMO-OFDM systems. Analysis for the optimum SI power allocation is also presented.
