Abstract :
The different QoS and data rate requirements of communication channels can be satisfied by varying one or more of the coding, digital modulation and spreading blocks. Keeping the transmission bandwidth fixed as in IS-95, four different interblock data rate configurations are compared. User powers are kept constant in the performance simulations. Various coding, modulation and spreading rate combinations yield different performance characteristics in AWGN, flat fading and multipath environments permitting trade-off decisions on choices of rate, QoS, and implementation
