Frequency-hopping spread spectrum (FHSS) transmission is the repeated switching of the carrier frequency during radio transmission to reduce interference and avoid interception. FHSS is useful to counter eavesdropping, as well as to obstruct thefrequency jammingof telecommunications and to enablecode-divisi...
The Frequency-Hopping Spread Spectrum (FHSS) is a means of transmitting radio signals by shifting a carrier across a number of channels with a pseudorandom sequence that the sending and receiving station knows beforehand. The method is used as a multiple
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 ...
跳频是一种通信技术的术语。跳频技术是一种扩展频谱通信方式，广泛应用于无线通信领域。其核心原理是在数据传输过程中，信号的载波频率会按照一定的规律和速率在多个频率之间切换。这种频率跳变的方式可以有效地提高通信系统的抗干扰能力和可靠性。接下来对跳频技术进行 跳频技术的核心思想是将通信信号在一个...
Direct Sequence Spread Spectrum (DSSS): designed originally by two vendors to increase the available speed on the wireless network. Divides the available 83.5 MHz spectrum (in most countries) into 3 wide-band 22 MHz channels. Uses an 11 bit spreading code to reduce the possible interference on...
