WebJul 29, 2013 · Abstract: Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. It is utilized as a multiple access method in the frequency-hopping code division multiple access (FH … WebOct 17, 2024 · Direct-sequence spread spectrum is a particular scheme for signal-spreading, which includes two complementary schemes called direct-sequence spread spectrum and frequency hopping spread spectrum. In the direct-sequence spread spectrum, the spreading code is contained within the transmitted signal to be used for spreading.
