cdma2000系统上行链路simulink仿真程序。(simulink uplink cdma2000 system simulation program.)

The implementation was built on Matlab/Simulink using fundamental components in Simulink to demonstrate how reliably complex modulation schemes can be built, cost effectively and efficiently [5]. The design of ZigBee transmitter using MSK modulation is shown in the Figure 1. Here we map input data bits to 8-chip PN sequences to be transmitted and results in a chip rate of two mega chips per second. After that, resultant chip sequence is send to the serial to parallel converter. It is used here to separate the odd and even bit indexed chips. Following this bipolar data formatting is performed and signal modulated with a 2.4 GHz carrier on the In Phase and QuadraturePhase data stream and adds it to get the required transmitter output signal.

此电子资料为小波与傅里叶分析基础，里面主要讲解有关小波和傅里叶的理论知识，和一些相关的应用。此书可以实践在实验上用matlab来实现。(This electronic data base wavelet and Fourier analysis, which is mainly explain the wavelet and Fourier s theory of knowledge, and a number of related applications. This book can be practiced using matlab to achieve experimentally.)
