Performance analysis of subspace projection techniques for interference excision in DSSS communications
R.S. Ramineni, Moeness G. Amin, Alan R. Lindsey · 2002
This paper presents the performance analysis of the interference excision techniques in direct sequence spread spectrum (DSSS) communications using orthogonal subspace projections. It is shown that this technique is sensitive to the errors in the instantaneous frequency (IF) estimate of the interference over segments of the bit period. This paper discusses the effect of two different types of errors on the receiver SINR and compares the performance of the block-wise processing to the single block projection approach.
