通信网络 ISM射频接收器的基带计算
Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) receivers use an external Sallen-Key datafilter and a data slicer to generate the baseband digital output. This tutorial describes the ISM-RF Baseband Calculator,which can be used to calculate the filter capacitor values ...

This file is used to simulate performance of the FMT system
with different modulation method in baseband。（该程序主要实现FMT系统差分编码下基带误码率分析！）
书籍 Digital Processing Optical Transmission
Optical communication technology has been extensively developed over the
last 50 years, since the proposed idea by Kao and Hockham [1]. However, only
during the last 15 years have the concepts of communication foundation, that
is, the modulation and demodulation techniques, been applied. This is pos ...
模拟电子 DA转换接口的射频IQ调制
 
Linear Technology’s High Frequency Product lineupincludes a variety of RF I/Q modulators. The purpose ofthis application note is to illustrate the circuits requiredto interface these modulators with several popular D/Aconverters. Such circuits typically are required to maximizethe v ...

To fully utilize the available spectrum for a wireless communication
system it is feasible to adapt to different situations
on the channel. In this paper a flexible OFDM
transmitter is presented together with basic theory behind
OFDM transmission. It is shown that high flexibility can
be obtained wi ...
模拟电子 RF至数字接收器的信号链噪声分析
 
Designers of signal receiver systems often need to performcascaded chain analysis of system performancefrom the antenna all the way to the ADC. Noise is a criticalparameter in the chain analysis because it limits theoverall sensitivity of the receiver. An application’s noiserequirem ...
无线通信 移动无线终端导航AFE和数据转换器
Abstract: High-speed and low-speed data converters serve critical functions in modern broadband mobile radios. This application note outlines how todetermine high-speed data converter performance requirements in baseband sampling radio architectures. Also, system partition strategies andadvantages ...

技术资料 Specifying the Jitter Performance
The question of sample-clock quality is a perennial one for digital audio equipment designers. Yet most chip makers
provide very little information about the jitter performance of their products. Consequently, equipment designers
sometimes get burnt by jitter issues. The increasing use of packet-bas ...
