qpskawgn

QPSK modulation system with recover loops(This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. The transmitter?s symbol period is T and set to a value of 100 ms. The symbol period at the receiver is Tr. The model will produce six windows: Two constellation plots and two eye diagrams (for the real part only), at the output of the matched fi lters and after the recovery loops a plot of the phase error (output of the NCO) and a plot of the fractional timing error (used in the interpolator). The frequency off set at the receiver is denoted by deltaf. The model simulates the transmission of 8000 QPSK symbols.)

本书把 MATLAB 当作一种技术编程语言来教，向学生展示如何编写简洁高效，有充分 根据的程序。本书不主张把 MATLAB 数以百计的函数全部介绍给大家，而是教给学生怎样使用 MATLAB 语言，以及如何使用网上在线工具去加载你所需要的函数。(The book MATLAB as a technology programming language to teach, show students how to write simple and efficient, have fully According to the program. This book does not advocate the MATLAB hundreds of function is introduced to you all, but teach students how to use MATLAB language, and how to use the online tools you need to load the function.)
