A scalable pipelined complex valued matrix inversion architecture
(2005) IEEE International Symposium on Circuits and Systems (ISCAS), 2005 In IEEE International Symposium on Circuits and Systems (ISCAS) p.44894492 Abstract
 This paper presents a fast, pipelined and scalable hardware architecture for inverting complex valued matrices. The matrix inversion algorithm involves, a QRfactorization based on the squared Givens rotations algorithm, the application of a recurrence algorithm for inversion of an upper triangular matrix R, and a matrix multiplication of R<sup>1</sup> with Q. We show that traditional triangular array architectures employing O(n<sup>2</sup>) communicating processors can be mapped onto a scalable linear array architecture with only O(n) processors. The linear array architecture avoids drawbacks such as nonscalability, large area consumption and low throughput rate. The architecture is implemented using arithmetic... (More)

The linear array architecture avoids drawbacks such as nonscalability, large area consumption and low throughput rate. The architecture is implemented using arithmetic operations with 12 bit fixedpoint representation. The hardware implementation will be used as a core processor in a realtime smart antenna system (Less)
