Positive definite kernels for identification and equalization of Indoor Broadband Radio Access Network

We consider a transmission system, where the transmitted symbols are subject of inquiry. The kernels-based algorithms are of great importance to many problems. The channel identification and equalization operate by a proposed algorithm based on positive kernel method for multi-carrier code division multiple (MC-CDMA) system. Two practical selective frequency fading channels are considered; they are called broadband radio access network (BRAN A and BRAN B) normalized by ETSI. To conceive the proposed algorithm, we focused on the positive definite kernels. Numerical simulations show that the algorithm confirms the good performance for different Signal to Noise Ratio (SNR). We use zero forcing (ZF) and minimum mean square error (MMSE) equalizers for the equalization MC-CDMA system.
