dc.description Conference Paper
dc.description.abstract In this paper, we propose a parallel and pipelined VLSI architecture for a circulant approximated equalizer for the MIMOCDMA systems. The FFT-based tap solver reduces the Direct-Matrix-Inverse of the size (NF x NF) to the inverse of O(N) sub-matrices of the size (N x N). Hermitian optimization and tree pruning is proposed to reduce the number and complexity of the FFTs. A divide-andconquer method partitions the 4£4 sub-matrices into 2x2 sub-matrices and simplifies the inverse of sub-matrices. Generic VLSI architecture is derived to eliminate the redundancies in the complex operations. Multiple level parallelism and pipelining is investigated with a Catapult C High-Level-Synthesis (HLS) methodology. This leads to efficient VLSI architectures with 3x further complexity reduction. The scalable VLSI architectures are prototyped with the Xilinx FPGAs and achieve area/time efficiency.
