摘要： A decoder dynamically terminates iteration calculations in the decoding of a received convolutionally coded signal using quality index criteria. In a turbo decoder with two recursion processors connected in an iterative loop, at least one additional recursion processor is coupled in parallel at the inputs of at least one of the recursion processors. All of the recursion processors perform concurrent iterative calculations on the signal. The at least one additional recursion processor calculates a quality index of the signal for each iteration. A controller terminates the iterations when the measure of the quality index criteria exceeds a predetermined level.

摘要： The error detection method includes decoding a portion of each control channel that is simultaneously received by a user equipment (UE) in a wireless communication system. The UE is provided with techniques to determine if one or more of the control channels were successfully received during the decoding step. If more than one control channel was successfully received, the method selects only one of the successfully received control channels based on calculated path metric differences (PMD) that serve as a "tie-breaking" mechanism to select the correct control channel for a particular UE.

摘要： Techniques to adjust the setpoint of a power control loop in a wireless communicaton system. The setpoint may be adjusted based on frame status indicative of erased/good decoded frames, one or more (typically soft) metrics indicative of the confidence in the decoded results, power surplus/deficit indicative of the difference between the received signal quality and the setpoint and a threshold Eb/Nt needed for the desired level of performance, or a combination thereof. The metrics may include re-encoded symbol error rate, re-encoded power metric, modified Yamamoto metric, minimum or average LLR among decoded bits, number of decoding iterations, and possibly others, The setpoint may be adjusted in different manners and/or by different amounts depending on the above-noted factors. The techniques may be employed for forward and/or reverse links in CDMA systems.

摘要： A decoding apparatus and decoding method for performing iteration decoding the suitable number of iterations, and thereby securing the desired transmission quality while decreasing the processing delay. Turbo decoder 301 iterates error correcting decoding on input coded sequences. Error checker 302 decodes an error detecting code contained in a decoded result of the error correcting decoding, and checks whether or not an error remains in the decoded result in turbo decoder 301. Iteration controller 303 instructs turbo decoder 301 to continue the iteration decoding until the number of iterations in the iteration decoding is more than or equal to the constraint number of iterations and error checker 302 determines no error in the decoded result.

摘要： Disclosed is an apparatus for stopping iterative decoding in a turbo decoder performing iterative decoding on a received frame comprised of information bits and then outputting the iteratively decoded results. A turbo decoder sequentially outputs absolute LLR (Log Likelihood Ratio) values associated with the respective information bits of the received frame by the iterative decoding, and stops the iterative decoding in response to a stop command for the iterative decoding. A minimum LLR detector selects a minimum value M(i) among the sequentially output absolute LLR values. A controller issues a command to stop the iterative decoding, if the minimum value M(i) is larger than a first threshold determined based on a minimum value F min among absolute LLR values output through previous iterative decoding.
