In this paper, a candidate architecture for LTE-Advanced receiver is proposed. Based on the combination of MIMO techniques and flexible spectrum access, LTE-Advanced terminals will require an increasing complexity of the front-end part. To reduce the complexity of the analog front-end, an innovative architecture is introduced based on the merging between the double IQ and code multiplexing structure. Simulation results show that, in a Gaussian case, the bit error rate does not increase
