Abstract: A receiver receives communications over a communication channel, which may distort an incoming communication signal. In order to counter this distortion, the frequency response of the receiver is manipulated by adjusting several frequency response parameters. Each frequency response parameter controls at least a portion of the frequency response of the receiver. The optimal values for the frequency response parameters are determined by modifying an initial set of values for the frequency response parameters through one or more of stochastic hill climbing operations until a performance metric associated with the receiver reaches a local maximum. The modified values are displaced through one or more mutation operations. The stochastic hill climbing operations may subsequently be performed on the mutated values to generate the final values for the frequency response parameters.

Abstract: A clock data recovery (CDR) mechanism qualifies symbols received from the data detector prior to using those symbols to compute a timing gradient. The disclosed CDR mechanism analyzes one or more recently received symbols to determine whether the current symbol should be used in computing the time gradient. When configured with a Mueller-Muller phase detector, the timing gradient for the received signal is set to zero if the current symbol is a ?2 or a +2 and the previous symbol is non-zero. Otherwise, the Mueller-Muller timing gradient is evaluated in the traditional manner. When configured with a minimum mean-squared error phase detector, the timing gradient for the received signal is set to zero if the previous symbol is non-zero. Otherwise, the minimum mean-squared error timing gradient is evaluated in the traditional manner.

Abstract: Techniques for limiting the growth of errors in decoded data words that arise from bit errors incurred during transmission. The growth of 3+ bit errors in the decoded data word is limited at the expense of a higher number of two bit errors, which are correctable using practical error correcting codes.
