Adaptive forgetting factor recursive least squares for blind interference suppression in DS/CDMA systems
Vikram Krishnamurthy, Sumeetpal Sidhu Singh · 2002
We develop an adaptive forgetting factor blind RLS algorithm for code-aided suppression of multiple access interference (MAI) and narrow-band interference (NBI) in DS/CDMA systems. The algorithm optimally adapts both the forgetting factor and the weight vector of the linear multiuser detector using the received measurements. Simulations show that the proposed algorithm is superior to the blind RLS algorithm in dynamic environments.
