OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...

We’ve done quite a bit with Google Sheets and signal processing: we’ve generated signals, created filters, and computed quadrature signals. We can pull all that together into an educational model for ...

Signal modulation is one of the most basic and important concepts in the RF industry. It consists of using the variation of one or more parameters of a carrier signal to transmit information, ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...
