Abstract:
|
In this paper, a streamlined MIMO Kalman equalizer
architecture is proposed to extract the commonality in the
data path by jointly considering the displacement structure of the
transition matrix and the block-Toeplitz structure of the channel
matrix. Finally, an iterative Conjugate-Gradient based algorithm
is proposed to avoid the inverse of the Hermitian symmetric
innovation correlation matrix in Kalman gain processor. The
proposed architecture not only reduces the numerical complexity
to O(F log F) per chip, but also facilitates the parallel and
pipelined VLSI implementation in real-time processing. |
