FPGA Implementation of a MIMO Receiver Front - end for UMTS

great attention in the past years as a means to boost capacity of wireless communication systems. Multiple antennas at the transmitter and receiver are used to exploit the spatial diversity in a rich scattering environment to concurrently transmit multiple data streams in the same frequency band thereby increasing spectral efficiency. Besides the actual MIMO decoder a significant part of the implementation complexity of such a system turns out to be in the receiver front-end. In this paper an efficient implementation of a UMTS-based MIMO receiver front-end based on a new method for the efficient realization of a MIMO channel estimation is presented. We also discuss the implementation of the RAKE receiver and the frequency-offset estimation.
