A Novel VLSI Implementation of MIMO OFDM for 3GPP LTE


In this paper, Distributed Arithmetic (DA) based K-best List Sphere Detector (LSD) for a 3GPP Long Term Evolution (LTE) receiver is proposed. The K-best LSD block implemented with the use of DA, reduces the size of the parallel hardware multiply-accumulate. These DA based blocks has an improvement in terms of area. This design has minimal hardware and computational complexity to meet the requirements of LTE standard. The VHDL coding for K-best LSD using DA for LTE is downloaded onto Spartan xc3s100e-4vq100 and results were verified.
