Disadvantages of using AM for DSSS/FHSS Spread Spectrum?
Roy Lewallen wrote:
"How did you conclude from this statement in Terman that the bandwidth required by FM is twice that required by AM?" Easy, I turn up the peak deviation intil twice the bandwidth is occupied with FM as would be required for AM. It is arbitrary and depends on peak deviation. If you make the deviation less than half the modulating frequency, the bandwidth occupied will be about the same as required for AM. Best regards, Richard Harrison, KB5WZI |
