Joint synchronization and detection from multiple samples per symbol

Summary form only given, as follows. The authors investigate the problem of sequence estimation, in the presence of a timing uncertainty, from samples of the output of a matched filter taken at an integer multiple of the symbol rate. The effects of sampling rate and signaling pulse shape on both delay and sequence estimation performance are studied by means of lower bounds on the mean-square estimation error and error probability, respectively. Further, algorithms for delay and sequence estimation, based on joint maximum-likelihood processing of the data samples, and an iterative algorithm motivated by the expectation-maximization (EM) algorithm are introduced. The general results are applied to the case of binary antipodal signaling and rectangular pulse shapes.
