伪随机码或称PN码，是扩频通信中不可缺少的一种序列。扩频通信，简单的说来就是通过一组相关性很强的伪随机序列，使原有的信号按照伪随机序列的特性出现。(Said pseudo-random code or PN code, spread spectrum communication is an indispensable sequence. Spectrum, simple to say is highly relevant by a group of pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence appears.)

Image enhancement code using matlab algorithm. Very good performance.

OFDM is one of the best physical-layer candidates for cognitive radio (CR) systems, but rectangular pulse shaping gives rise to large spectrum sidelobes and interferes with the licensed user on the adjacent band. In this paper, an approach is derived based on the signal continuity to measure the spectral decay rate of the shaping pulse for OFDM.
