Orthogonal Frequency Division Multiplexing (OFDM) is a modulation schema that due to the high spectral efficiency and the simplicity of the receiver implementation is the most common system for using ...

Orthogonal Frequency Division Multiplexing (OFDM) has become the cornerstone of modern broadband wireless communications, owing to its spectral efficiency and robustness to multipath fading. However, ...

The determination of the carrier frequency of a particular pulsed signal is largely a function of the receiving system. The typical manual receiver has a calibrated frequency display and a tuning aid ...

Lately I’ve seen a number of discussions about adding a frequency offset to an ATSC 1 signal to reduce interference. The issue came to light when it was discovered that at least one major manufacturer ...

GLONASS satellites traditionally use L1 and L2 frequency division multiple access (FDMA) signals. FDMA is characterized by a different transmit frequency for each satellite. Newer satellite ...
