RECEIVER HAVING A VARIABLE THRESHOLD SLICER STAGE AND A METHOD OF UPDATING THE THRESHOLD LEVELS OF THE SLICER STAGE

摘要

A receiver having a variable bit slicer for detecting bits in a demodulated signal, comprises a demodulator ( 14 ) for deriving a demodulated bit rate signal, means ( 36 ) for storing a plurality of threshold values, each of the threshold values being selectively adjustable, means ( 28, 38 ) for selecting the threshold value for comparison with the current bit signal (SSUBn/SUB) in response to a sequence of N bits (where N is at least 2) (BSUBn-1/SUB, BSUBn-2/SUB) received prior to the current bit (BSUBn/SUB) and means ( 38, 40 ) for using the current bit to update the selected threshold value. Also disclosed is a method of dc offset correction.
