说明：  SLM算法降低OFDM通信系统中的PAPR，使用matlab进行仿真(SLM algorithm reduces PAPR in OFDM communication system, and matlab is used for simulation)

这是一个关于ofdm在802.11协议下的源码，很有参考价值，希望对大家有用(This is a matter of OFDM in the 802.11 protocol under the source, a good reference, in the hope that useful)

非合作博弈论在认知无线电中的功率控制方法探讨 (Non-cooperative game theory in cognitive radio power allocation)

labwindows CVI 8.0 下调试通过的gprs，建立过程和udp通讯。(with labwindows cvi8.0,gprs connection had been programmed,and udp test is ok )

Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assuming BPSK. Brute force Monte Carlo approach is unsatisfactory (takes too long) to find the BER curve. The computation uses a quasi-analytic (QA) technique that relies on the estimation (approximate one) of the information-bits Weight Enumerating Function (WEF) using A simulation of the convolutional encoder. Once the WEF is estimated, the analytic formula for the BER is used.(Computes BER v EbNo curve for convolutional encoding/soft decision Viterbi decoding scheme assuming BPSK.
