Nice explanation is given for spread spectrum. In this you have given a block diagram of DSSS with PN sequence and chip generator blocks after phase modulation block. The original information in discreet form, is firstly modulated with chip generator to expand its base bandwidth .Then further it undergoes PSK or QPSK or anyother keying so that final cont signal is available for transmission, so shouldn't PSK block come after chip generator?? Is alteration of signal base bandwidth by PN code is done initially and then its phase keyed to be transmitted or phase shift keying is done initially then this is further SS modulated using PN codes? which order it takes place? Please do clarify this point sir.

How you are claiming that DSSS is better immune to jamming than FHSS? It’s much easier to jammed B.W separated in DSSS, while in FHSS it’s hoping in different channel at different times. If jammer is sending noise on one channel only specific chunk of data would required to retransmit in FHSS. Thank you though for working presentation of DSSS. Keep it up
