QNX-Bluetooth-Sample

这是一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT， 上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模 块，并统括系统性能的仿真验证了系统设计的可靠性 (OFDM full version of the source code, including coding, modulation, IFFT, Upper and lower frequency, Gaussian channel model, FFT, PAPR suppression, a variety of synchronization, demodulation and decoding module, and system performance of the omnibus simulation verify the reliability of the system design)

不同的相邻分组数目v实现的pts抑制ofdm峰均比的算法，可以仿真出v越大，papr的性能越好(Different number of adjacent sub-v realize the pts OFDM PAPR suppression algorithms, simulation of v can be greater, papr better performance)

阵列信号处理的基本MUSIC算法以及改进的基于子空间投影加权的MUSIC算法，以及全空间加权MUSIC算法对DOA进行估计，以及几种算法的均方根误差比较(The basic MUSIC algorithm of array signal processing, the improved MUSIC algorithm based on subspace projection weighted, and the full space weighted MUSIC algorithm for the estimation of DOA, and the root mean square error comparison of several algorithms)

说明：  C# 写的NetRemoting通信例子 双向通信(NetRemoting Communication Example Written in C# Two-way communication)

基于深度限幅的OFDM峰均比抑制器的设计 （限幅法是最简单直接的一种，以降低误码率性能 频谱畸变和计算复杂度为主要代价。）(matlab OFDM)
