Problem 1: Briefly describe the concept of spread spectrum technique and list three important benefits.
Problem 2: 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.
Problem 3: 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?
