We simulate uncoded BER of BPSK modulated data as a function of SNR -in an AWGN channel -in a Rayleigh fading channel -in an AWGN channel when direct sequence spreading is used and compare results to the theoretical ones. We assume coherent receiver and perfect synchronization.

Performance analysis of wireless networking with interleaving on the receiver side over Rayleigh fading channels.

In 揚erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier. The receiver provides a correlator for each carrier, and ...

用于通信信道服从莱斯分布的仿真。注意：适用于产生0101码，并且用星座图判别误码率的仿真。

Lithium–sulfur batteries are a promising energy-storage technology due to their relatively low cost and high theoretical energy density. However, one of their major technical problems is the shuttling of soluble polysulfides between electrodes, resulting in rapid capacity fading. Here, we present ...

介绍衰落信道中的数字通信原理及技术。作者：Marvin K. Simon和Mohamed-Slim Alouini。感觉内容深入浅出，适合作为无线通信方向的硕士或博士研究生的参考书。

Regardless of the branch of science or engineering, theoreticians have always been enamored with the notion of expressing their results in the form of closed-form expressions. Quite often, the elegance of the closed-form solution is overshadowed by the complexity of its form and the difficulty in ev ...
