There are some of the advantages of frequency hopping spread spectrum (FH-SS) given below :
- It has less distance effect.
- Provide the greatest amount of spreading.
- The bandwidth of these systems is large.
- It has a short acquisition time.
- Best discrimination against multi-path.
- Very large bandwidth.
- The synchronization is not greatly dependent on distance.
- This system can be programmed to avoid some part of the spectrum.
There are some of the disadvantages of Frequency hopping spread spectrum (FH-SS) given below :
- It needs complex and costly digital frequency synthesizers are required to be used.
- It needs error detection.
- The processing gain is higher than that of a direct sequence spread spectrum.
- This system is not useful for the range and range rate measurement.
- The modulation scheme has become obsolete.
Some more advantages of FH/SS compared to DS/SS is given below :
- FS/SS is less susceptible to be near-far problems than DS/SS.
- The processing gain is higher than that of system DS/SS.
- FH/SS can produce signals of wider bandwidth than DS/SS.
- In FS/SS the problem of a relative power level of co-channel signals is not critical as than DS/SS.
