Abstract :
We investigate adaptive minimum bit error rate (MBER) multiuser receivers for single (SC) and multicarrier (MC) CDMA systems in frequency selective channels. The approximate minimum BER (AMBER) receiver is examined and a Newton adaptive implementation is presented. Simulations results show how the proposed algorithm outperforms minimum mean squared error based algorithms.
