An efficient Architecture for Multiband-MIMO with LTEAdvanced Receivers for UWB Communication Systems

The emerging ultra wideband (UWB) system offers a great potential for the design of high speed short-range wireless communications. In order to satisfy the growing demand for higher data rates, one possible solution is to exploit both spatial and multipath diversities via the use of multiple-input multiple-output (MIMO) and proper coding techniques. In this paper, candidate architecture for LTE Advanced receiver is proposed. Based on the combination of MIMO techniques and flexible spectrum access, LTE-Advanced terminals will require the increasing of the analog front-end complexity. This is a general framework is proposed to analyze the performance of multiband UWB-MIMO systems regardless of specific coding schemes. Simulation and measurement results show that, in a Gaussian case, the bit error rate is similar when using the proposed architecture and the state of the art front-end stack-up structure. A complexity evaluation study reveals significantly reduced power consumption of the proposed single front-end architecture. Finally, simulation results are presented to support the theoretical analysis.
