Uplink Interference Cancellation in HSPA: Complexity Analysis
Uplink Interference Cancellation in HSPA: Complexity Analysis
We first provide an overview of the interference cancellation schemes and assumed architecture. In particular, we are interested in the group IC scheme with scheduling. Then we present the HSPA uplink system for a loaded VoIP application scenario, for which we perform a complexity analysis.
