ABSTRACT:
Methods and systems are provided for communicating encoded data. L received encoded signal values including soft information are received and transformed to L data symbols. In various embodiments, the L received encoded signal values are demodulated and the demodulated L received encoded signal values are convolutional decoded using a rate one convolutional decoder having only one output symbol per input symbol to provide the L data symbols, wherein the L received encoded signal values are convolutional encoded using a rate one convolutional encoder having only one output symbol per input symbol. In other embodiments of the present invention the L received encoded signal values are transformed using associated spectral energy at a plurality of frequency ranges within a bandwidth of a channel over which the L received encoded signal values are received for at least one of the L received encoded signal values.
