Description: 本书是关于无线衰落信道方面的一本好书，书中内含MATLAB代码！
-All relevant components of a mobile radio system, from digital modulation techniques over channel coding through to network aspects, are determined by the propagation characteristics of the channel. Therefore, a precise knowledge of mobile radio channels is crucial for the development, evaluation and test of current and future mobile radio communication systems. This volume deals with the modelling, analysis, and simulation of mobile fading channels and provides a fundamental understanding of many issues that are currently being investigated in the area of mobile fading channel modelling. The author strongly emphasises the detailed derivation of the presented channel models and conveys a high degree of mathematical unity to the reader.
Introduces the fundamentals of stochastic and deterministic channel models
Features the modelling and simulation of frequency-nonselective fading channels (Rayleigh channels, Rice channels, generalized Rice channels, Nakagami channels, various types Platform: |

Description: 主函数Alamouti(Nr,max_snr,max_err_symbol,symbol_per_frame)
调用函数QpskMapping(psudo_bit_sequence)－－二进制数据到QPSK信号的变换
调用函数RayleighCH(Nr,Nt)－－瑞利衰落信道模拟
仿真示例：
Alamouti(1,12,20,24)
说明：
1.2根发射天线、1根接收天线
2.最高信噪比为12dB，即仿真范围为0dB到12dB
3.在每个信噪比条件下,误符号数超过20即停止该信噪比条件下的仿真
4.每一帧数据为24个QPSK符号
综合仿真函数SimAlamouti(max_snr,max_err_symbol,symbol_per_frame)
具有一根接收天线系统的SER性能与二根接收天线的系统SER性能比较
SimAlamouti(12,20,24)
参数说明：
1.max_err_symbol的取值直接影响了仿真的精度：取值越大，精度越高，误符号率曲线也更平滑；但需更长的仿真
时间
2.一般max_snr小于15dB，程序中snr为信号噪声功率比
3.本程序仿真时未考虑帧与帧之间，信道衰落系数的相关性，因此symbol_per_frame一定程度上表征了信道相关时
间的大小，即在symbol_per_frame个QPSK信号发送时间内，信道衰落系数是不变或缓变的，而在下一帧数据中，
信道衰落系数可以认为已变成另一值
4.本程序假定在接收端已通过信道估计获得信道衰落系数-ALAMOUTI performs Monte-Carlo simulation and estimates Bit Error Rate
(BER) of Alamouti Scheme [1] over Rayleigh channel. The scheme presumes
2 transmit (Tx) and arbitrary number of receive (Rx) elements.
If Rx=1 (one receive element) ALAMOUTI is transformed to the order 2
transmit diversity scheme with Maximum Ratio Combining (MRC). The
modulation format is MPSK with arbitrary order M which can be
controlled by user. Platform: |

Description: 中继信道下 利用EXIT算法进行中继选择， Lajos Hanzo 实验室的成果(In this paper, we have proposed and investigated an
attractive joint source coding, channel coding, and modulation
(JSCM) scheme for a two-way relaying system. We commence by
quantifying the achievable capacity of the corresponding two-way
relay channel before proposing low-complexity source coding
schemes for concatenation with bandwidth- and power-efficient
coded modulation schemes. Extrinsic information transfer (EXIT)
charts are used to investigate the decoding convergence of the joint
source and channel decoder and for the overall system design. The
quality of the decoded source signals is quantified using the bit
error ratio (BER) metric. It is found that the two-way-relay-based
JSCM scheme is capable of attaining a combined coding and relaying gain of 5.7 dB over the conventional noncooperative JSCM
scheme when communicating over uncorrelated Rayleigh fading
channels in an outdoor environment) Platform: |
