Recursive adaptive equalizer for SMSK data links

摘要

SMSK data link degradation in future and immediate past bits produced by carrier phase error and small errors in the sampling instant are reduced by a recursive adaptive equalizer having a feedforward stage with adjustable weight for each future bit to be corrected and a feedback stage with adjustable weight for each immediate past bit to be corrected. The weights are controlled by a controller which samples the output and adjusts each weight until the output is correct.
