Description: To improve the performance of short-range wireless communications, channel quality must
be improved by avoiding interference and multi-path fading. Frequency hopping spread
spectrum (FHSS) is a transmission technique where the carrier hops frequency to
frequency. For frequency hopping a mechanism must be designed so that the data can be
transmitted in a clear channel and avoid congested channels. Adaptive frequency hopping is
a system which is used to improve immunity toward frequency interference by avoiding
using congested frequency channels in hopping sequence. Mathematical modelling is used
to simulate and analyze the performance improvement by using frequency hopping spread
spectrum with popular modulation schemes, and also the hopping channel situations are
investigated.
