Abstract In this paper, practical approaches to implement the suppression of adjacent channel interference for direct digital six‐port receivers using compact integrated‐circuit dispersive delay lines are described and discussed in detail. Additional interference at the receiver output due to phase errors in the implementation is analyzed and calculated. Computer simulation results are provided, and further enhancement of the effectiveness of this suppression means is discussed. © 2002 John Wiley & Sons, Inc.
