DSP implementation of interference cancellation algorithm for a SIMO system

This paper presents an implementation on the fixed-point DSP chip of an interference cancellation algorithm containing a linear system. Difficulty in matching the algorithms performance obtained in full precision (IEEE float-point) implementation to those given by a finite precision tends to increase when the algorithms contains one or several linear system to solve. Gauss and Cholesky methods are implemented. Their performance results are showed and compared. The global implementation margins are discussed.
