Assignment Help:
In a CDMA system, the signal is spread over a large bandwidth by multiplying the transmitted symbol by a sequence of short pulses, also called chips. The system bandwidth is thus determined by the duration of a chip. If the chip duration is 0.26 µs and the maximum excess delay is 1.3 µs, into how many delay bins do the multipath components fall? If the maximum excess delay is 100 ns, is the CDMA systems wideband or narrowband?
