章节摘录

　　In the 1980s， the desire to increase the capacity and suite of services offered to mobile telephone customers prompted the development of digital communication systems. GSM，the digital mobile telephone standard in Europe， was deployed in the 1980s， whereas digital standards such as IS-54 and IS-136 （TDMA/FDM） and IS-95 （CDMA） were deployed in the United States in the 1990s. In addition to voice， digital radio is becoming more popular and television is increasingly delivered in a digital format （HDTV is an integrated digital video/audio format）. The corresponding communications link is a digital communications link.　　Data communication systems are also following this trend. One example is aeronautical telemetry.9 In aeronautical telemetry， the performance of an airborne "test article" is monitored by using a radio link to transmit the measurements output by a set of transducers to a ground-based monitoring station. The first aeronautical telemetry links were analog AM in the 1940s and analog FM in the 1950s. The output of each transducer modulated a separate carrier frequency to form the telemetry downlink. As airborne systems became more complex， more onboard measurements had to be collected and radioed to the ground. The use of separate carriers for each one proved unwieldy and uneconomical. By the 1970s， digital technology had progressed to the point where a new approach was possible. The transducer outputs were sampled to form a bit stream. The bit streams from all transducers were combined to form a composite bit stream that was used to modulate a single carrier. A digital version of FM （known as PCM/FM in the IRIG 106 Standard） became the most popular choice.　　……

•   书中对通信理论的讲述使用对比的方法论证，先连续时间，后离散时间。和其他讲述数字通信原理的书角度不太一样，但是讲述非常清楚，深刻。书中描述多为实际工程应用的具体例子，可谓理论联系实际。但国外讲数字通信的书有其一致性，都是以信号空间理论为基础论述展开的，本书亦然。非常值得一看。但不足之处在于国内影印版，印刷质量一般。
