Abstract
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.
