matlab的基本应用，和基础知识，ppt形式的讲解。(matlab basic applications, and basic knowledge, ppt form of explanation.)

Several Intelligent Vehicle applications require knowledge of the presence of objects in the path of the Host vehicle. Current approaches to this inpath decision process do not fully utilize the information available from the forward-looking sensor.

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.
