Briefly describe the concept of spread spectrum technique and list three important benefits.
a. Briefly describe the concept of spread spectrum technique and list three
important benefits.
b. Assume we wish to transmit a 64-kbps data stream using spread spectrum technique. Compute the bandwidth required for SNR = 0.1 and 0.01.
c. If the data stream is transmitted using a bandwidth of 64 kHz in an ordinary system (without spread spectrum), what is the SNR that could be tolerated without experiencing significant errors?
