DESCRIPTION This function initializes the pointers in the _pid structure 　　to the process variable and the setpoint. *pv and *sp are 　　integer pointers.

ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING FOR WIRELESS COMMUNICATIONS

This program generates OFDM (Orthogonal Frequency Division Multiplexing) signal and its spectrum. Also the guard interval (GI) is inserted.

I often need a simple function generator. Just to generate a certain frequency. After all the years I ve worked with electronics, I still haven t got me one. Even though I need it now and then, I just couldn t seem to justify the cost of one. So, standard solution - build one yourself. I designed a ...

A high-speed variable phase accumulator for an ADPLL architecture

Based on the frequency of single-chip design, can measure the number of low-frequency signal

Matlab demonstration script for frequency modulation.供刚接触到matlab的朋友使用

the magnitude responses in dB of the window functions in the frequency domain

ow-complexity orthogonal spectral signal construction for generalized OFDMA uplink with frequency synchronization errors

These routines model tropospheric radiowave propagation over variable terrain and calculates propagation loss vs. height and range. Propagation loss is displayed in dB contours on a height vs. range plot. TPEM is based on the split-step Fourier PE method and was originally developed from an early PE ...
