A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM)

A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication systems. This program is valuable for future researchers simulating systems that are too theoretically complex to analyze. Single-carrier QAM and multicarrier OFDM are compared to demonst ...

High-Frequency Oscillator Design

OSCILLATORS are key building blocks in integrated transceivers. In wired and wireless communication terminals, the receiver front-end selects, amplifies and converts the desired high-frequency signal to baseband. At baseband the signal can then be converted into the digital domain for further data p ...
