this study aims to better understand the effect of practice schedule and feedback providing types. in two separate experiments the contextual interference effect in bandwidth and self-control feedback conditions on relative and absolute timing learning was examined. in experiment i, the effect of contextual interference using bandwidth and self-control feedback on absolute timing learning (para...

Abstract— Per-Survivor Processing (PSP) provides a general framework for the approximation of Maximum Likelihood Sequence Estimation (MLSE) algorithms whenever the presence of unknown quantities prevents the precise use of the classical Viterbi algorithm. This principle stems from the idea that data-aided estimation of unknown parameters may be embedded into the structure of the Viterbi algorit...

In this paper, the problem of adaptive maximum a posteriori (MAP) symbol detection for the uncoded transmission as well as the problem of adaptive soft-input soft-output (SISO) demodulation for the coded transmission of data symbols over the time-varying frequency-selective channel are explored within the framework of the expectation-maximization (EM) algorithm. In particular, several recursive...

New generation cellular networks have been forced to support high data rate communications. The demand for high bandwidth data services has rapidly increased with the advent of bandwidth hungry applications. To fulfill the bandwidth requirement, high throughput backhaul links are required. Microwave radio links operating at high frequency bands are used to fully exploit the available spectrum. ...

An active RC matched filter, particularly useful for phase-coherent, coded or uncoded, binary or non-binary communication channels, is described. One detector circuit performs the equivalent of two simultaneous cross-correlations, avoiding the need for electronic multipliers, reference wave generation and phase synchronization. For example, only I circuits are needed in a receiver that is requi...

exchange extrinsic information during iterations. Simulation results indicate that the proposed receiver closely achieves the performance of the full complexity MAP within 2 to 3 iterations. The proposed scheme saves a significant amount of complerity in uncoded systems with a large number of transmit antennas and a high modulation order. I n coded systems, the PAMAP scheme becomes more benefic...

Linear (translation), hard-limited, and demod/remod types of satellite repeaters are considered in this paper. Both uncoded and coded multiple phase shift keyed (MPSK) signals are assumed to be transmitted through these repeaters. Relative performances of these repeaters in the presence of uplink and downlink noises are then compared quantitively. Probabilities of bit errors and the computation...
