Abstract :
We report the performance of blind orthogonally anchored adaptive algorithms for multiple access interference suppression in a land mobile satellite fading channel with asymmetrical Doppler power spectral density and lognormally distributed line of sight component, using code division multiple access (CDMA). Computer simulations show that the blind algorithms perform within 2 dB of a single user matched filter lower bound and provide significant improvement in capacity over the matched filter.
