maple 它的图形功能非常强大, 足以提供更多的关于函数的信息. 当然, 如果需要, 它的图形作适当改进即可满足出版要求. (maple graphics functions are very strong, and to provide more information about the function, of course. If necessary, it can improve the graphics for proper publication meet)

说明：  8psk调制解调的源码。给出调制前后符号的星座图和相关波形，指标对比。(8psk modulation and demodulation of the source. Given before and after the symbol constellation modulation and associated waveforms, index contrast.)

说明：  常规的单载波调制技术在带宽有限的测井电缆上的低传输速率制约着成像测井技术的发展。在分析测井 电缆传输特性和 OFDM 技术原理的基础上 ,设计了一种基于 OFDM 技术的测井电缆高速数据传输系统 ,并介绍了 基于 OFDM 技术的测井电缆高速数据传输系统的参数设计和工作原理 ,给出了不同长度测井电缆上的测试结果。 电缆实测结果表明 ,在 7 000 m长的测井电缆上 ,基于OFDM 技术的测井电缆高速数据传输系统可获得900 kbit / s 以上的数据传输速率和低于 5E28 的误码率。当变压器的接入模式为 Mode2II时 ,系统最高的数据传输速率可达到 1. 1 Mbit/ s。(To solve t he low data t ransmission rate problem in t he conventional single car rier mod2 ulation met hod for logging cable and enhance t he data t ransmission rate , a new data t ransmission system with high data t ransmission rate for logging cable is propo sed , which is based on t he Or2 t hogonal Frequency Division Multiplexing (OFDM) technology. The working principle of OFDM modem and t he procedure of data t ransmission system are al so presented and lot s of test s are car2 ried out on logging cables with different lengt hs. It is verified that t he data t ransmission rate can reach 900 kbit/s on 7 000 meter s logging cable wit h bit er ror rate (BER) lower t han 5E28 , and t he maximum data t ransmission rate is 1. 1 Mbit/s under Mode2II of t he t ransformer .)

watterson信道matlab仿真,瑞利衰落。。。。(This example shows how to simulate High-Frequency (HF) ionospheric channels, based on the models described in Recommendation ITU-R F.1487. In particular, it shows how to simulate the general Watterson channel model, and other simplified channel models used in the quantitative testing of HF modems. It makes use of the Rayleigh multipath fading channel object and the Gaussian and bi-Gaussian Doppler structures from Communications System Toolbox.)
