Pravin W. Raut, S.L.Badjate . Implementation of MIMO Encoding & Decoding in a Wireless Receiver. 2nd National Conference on Innovative Paradigms in Engineering and Technology (NCIPET 2013). NCIPET, 7 (March 2012), 26-31.
In this paper, we address the implementation of Multi-Input-Multi-Output (MIMO) Decoder embedded in a prototype of 3G / 4G Mobile receiver using FPGAs. This MIMO decoder is part of a multi-carrier code division multiple-access (MC-CDMA) radio system, equipped with multiple antennas at both ends of the link that is able to handle up to 32 users and provides raw transmission bit-rates up to 125 Mbps. The task of the MIMO decoder is to appropriately combine the signals simultaneously received on all antennas to construct an improved signal, free from interference, from which to estimate the transmitted symbols. The main motto of this is to design & Implement the FPGA based MIMO Encoder and Decoder. The Data links for Two symbol period were established and found that the MIMO decoder outputs follows the MIMO Encoder input. We report results using FPGA devices of the Xilinx family
