Claim Text:
1. A method of producing adaptive thresholds in a binary frame based communication system, comprising: collecting, with a frame bit sample collector, Kst samples of a received signal corresponding to a start bit at a start of a frame; computing, with a frame bit parameter estimation device, an estimate of a received signal parameter Pst of the start bit; adjusting, with a frame bit threshold calculation device, a start threshold based upon the Pst; collecting, with the frame bit sample collector, Ksp samples of the received signal corresponding to a stop bit at an end of a frame, wherein the Kst and Ksp samples are collected separately; computing, with the frame bit parameter estimation device, an estimate of a received signal parameter Psp of the stop bit; and adjusting, with the frame bit threshold calculation device, a stop threshold based upon the Psp wherein the first and second thresholds are applied to the received signal.
