Wiener filter based on tracking a priori SNR using Decision-Directed method, proposed by Scalart et al 96.

说明：  桥大学的YANG 和拉曼工程大学的 DEB 模拟布谷鸟的寻窝产卵行为, 提出一种新的智能优化算法 —— 布谷鸟搜索算法( Cuckoo Search) [9]。这种算法主要 基于布谷鸟的巢寄生繁殖机理和莱维飞行( L† vy flights) 搜索原理两个方面, 目前, 利用布谷鸟搜索算法( CS)求解 优化问题的研究还处于起步阶段。(This demo program only implements a standard version of Cuckoo Search (CS), as the Levy flights and generation of new solutions may use slightly different methods. The pseudo code was given sequentially (select a cuckoo etc), but the implementation here uses Matlab s vector capability, which results in neater/better codes and shorter running time. )

设计一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(Designed a four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)
