Consider the following CDMA chip sequences for four users: A, B, C

Consider the following CDMA chip sequences for four users: A, B, C and D: A: (+1, +1, +1, -1, -1, +1, -1, -1) B: (+1, +1, -1, +1, -1,-1, -1, +1) C: (+1, -1, +1, -1, -1,-1, +1, +1) D: (+1,-1, +1, +1, +1, +1, -1, +1) a) The users want to transmit simultaneously the following bits: A: 1, B: 1, C: - (nothing), D: 0. The total result is received by the base station in a 3G cellular system. What is the resulting chip sequence received by the base station? b) At another time, the following chip sequence (-1, +1, +1, -1, +1, +3, -1, -3) has been received by the base station. Explain in detail how the base station determines which users (A, B, C, or D) have sent data and which bits were transmitted by each user?
