摘要： Data communication devices, methods, and systems are discussed in this application. In one embodiment, a receiving apparatus generally comprises a detector, an indicator, and a decision device. The detector can detect a number of data streams contained in a signal received on a single physical channel. Detection can be made by comparing a received signal with one or more predetermined sequences and identifying one or more of the plural predetermined sequences as being likely contained within the received signal. Each data stream can be associated with at least one predetermined sequences. The indicator can provide an indication of the data streams likely contained in the signal based on the identified sequences. A decision device can provide data defining a receiver configuration based on the indication, the receiver configuration being suitable for configuring a decoder to decode only the one or more data streams indicated as being likely contained in the signal.

摘要： A novel symbol estimation method produces intersymbol interference free symbols by detecting interfering symbols in an interfering channel. A channel estimate is refined for additional improvements. The method can lends itself as a serial or parallel algorithm implementation. The symbol estimation method includes using an initial estimate of received symbols and calculating a refined estimate of the received symbols using a channel estimate. The refined estimate is calculated by performing parameterization of intersymbol interference by symbols other than the symbol being refined and selecting a refined value for the symbol being refined by evaluating an optimization function. Symbol estimates are refined in multiple iterations, until a pre-determined iteration termination criterion is met. Parameterization of ISI contribution of other symbols results in reduced computation by reducing total number of unknown variables in the refinement operation.
