Optimal transmitter power control in interleave division multiple access (IDMA) spread spectrum uplink channels
Zvi Rosberg · IEEE Transactions on Wireless Communications · 2007
The optimal transmitter power control policy in an interleave division multiple access (IDMA) spread spectrum uplink channel is derived. The policy is applied to an IDMA channel with repetition code and a chip-by-chip maximum-likelihood decoder whose sum-rate is compared to the capacity of a linear minimum mean square error multiuser detector and to the Cover-Wyner capacity
