Webb1 maj 2000 · HRMA is based on slow frequency hopping spread spectrum (FHSS) and takes advantage of the time slotting necessary for frequency hopping. HRMA applies a hop reservation and handshake mechanism on every hop, to guarantee collision-free data transmission in the presence of hidden terminals; this is accomplished by allowing a pair … Webb跳频扩频（Frequency-Hopping Spread Spectrum，FHSS）技术是一种常用的扩频通信物理层技术。通信时，发送端根据扩频码序列去进行移频键控（FSK）调制，使载波的频率不断地跳变。接收端由于有与发送端完全相同的扩频码序列，从而可以跟踪频率不断跳变的信号并对信号进行解扩，然后通过解调正确地恢复原有的信息。图1是FHSS通信系统的简化 … Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many frequencies occupying a large spectral band. The changes are controlled by a code known to both transmitter and receiver. FHSS is used to avoid interference, to prevent eavesdropping, and to enable code-division multiple access (CDMA) communic… smallest six seater car

WebbBecause the bandwidth of an FHSS system only depends on the tuning range, it can be hopped over a much wider bandwith than an DSSS system. Since the hops generally result in phasediscontinuity (depending on the particular implementation) a noncoherent demodulation is done at the receiver.
