Iterative Timing Recovery and Turbo Equalization
نویسندگان
چکیده
Iteratively decodable error correction codes enable operation at very low SNR, which exacerbates the timing recovery problem. We describe a scheme for joint timing recovery and turbo equalization that significantly lowers the SNR requirement when compared to a conventional receiver that separates timing recovery and turbo equalization. We also investigate the Cramér-Rao bound as a tool for evaluating the performance of iterative timing recovery schemes.

Performance of Interpolated Timing Recovery in Perpendicular Magnetic Recording Channel
Magnetic recording systems employ conventional VCO-based timing recovery to synchronize the readback signal and the sampler, which is expensive to implement. To get rid of this VCO, a fully digital timing recovery known as interpolated timing recovery (ITR) is utilized. This paper investigates the performance of the ITR architecture in magnetic recording channels with and without error-control ...
متن کاملLower Bounds for the Performance of Iterative Timing Recovery at low SNR
The push for higher recording densities has motivated the development of iterative errorcontrol codes of unprecedented power, whose large coding gains enable low error rates at very low SNR [1] [2]. In addition, the iterative decoding technique has been extended to turbo equalization, where the equalizer and the decoder iterate [3]. Consequently, timing recovery, which typically derives no bene...
متن کاملJoint Timing Recovery and Turbo Equalization for Coded Partial Response Channels
We propose a method for jointly performing timing recovery and turbo equalization on partial response channels with error-correction codes. The proposed detector uses soft decisions from previous turbo iterations to improve timing estimates before the next, and each iteration is only marginally more complex than that of a conventional turbo equalizer. As compared to a conventional receiver with...
متن کاملIterative Timing Recovery with the Split-Preamble Strategy for Coded Partial Response Channels
This paper proposes a modified per-survivor iterative timing recovery scheme, which exploits a new split-preamble strategy in conjunction with a per-survivor processing soft-output Viterbi algorithm (PSPSOVA). The conventional split-preamble strategy places a preamble at the beginning of a data sector and uses it to run a phase-locked loop during acquisition to find an initial phase/frequency o...
متن کاملComdined Turbo Block Decoding and Equalisation
In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...
