Adaptive minimum bit error rate receiver for CDMA-based block transmission systems

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 p...

Description
Summary: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.
