References about frequency hopping communication

Hi,

wireless networks often employ spread-spectrum
encodings that multiple carrier frequencies to transmit data. The specific
form of spread spectrum known as ``frequency hopping'' cycles through a
sequence of frequencies, transmitting some bits of the message on each.


Frequency Hoping Spread Spectrum (FHSS)

Signal is broadcast over seemingly random series of radio frequencies
A number of channels allocated for the FH signal
Width of each channel corresponds to bandwidth of input signal
Signal hops from frequency to frequency at fixed intervals

Transmitter operates in one channel at a time
At each successive interval, a new carrier frequency is selected
FHSS Using MFSK

attached is a excellent doc on FH Vs DS

Hello
you can see "CDMA" COURSE
or have CDMA references.

Digital communication, poakis , in this forum has a section about this topics.

This is a good collection of different articles on spread spectrum and frequency hopping...a collection various online articles
