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?
