摘要： Aspects of a method and system for decoding single antenna interference cancellation (SAIC) and redundancy processing adaptation using frame process are provided. A receiver may decode video, voice, and/or speech bit sequences based on a first decoding algorithm that may utilize data redundancy and that may impose physical constraints. The receiver may also decode a bit sequence based on a second decoding algorithm that utilizes SAIC. The first and second decoding algorithms may be adapted to perform in parallel and a decoded received bit sequence may be selected based on a redundancy verification parameter. The first and second decoding algorithms may also be adapted to be performed sequentially where the subsequent decoding operation may be conditioned to the initial decoding operation. Moreover, either the first or the second decoding algorithm may be selected for decoding the received bit sequence. The selection may be based on noise and/or interference measurements.

摘要： A channel dispersion estimation algorithm(s) may be implemented within a channel length estimation module of a multi-branch equalizer processing module that disables a branch of the multi-branch equalizer processing module when the channel length or channel delay spread associated with received radio frequency (RF) bursts exceeds a predetermined threshold. The channel dispersion estimation algorithm identifies when the radio frequency (RF) bursts have a channel length or channel delay spread that can affect receiver performance. The channel length estimation module may disable interference cancellation by a branch of the multi-branch equalizer processing module in response to such a channel length or channel delay spread.

摘要： This invention provides channel dispersion estimation algorithm(s). This channel dispersion estimation algorithm(s) may be implemented within a channel length estimation module of a single-branch or multi-branch equalizer processing module that enables interference cancellation when the channel length or channel delay spread associated with received radio frequency (RF) bursts compares unfavorably to predetermined thresholds. The channel dispersion estimation algorithm identifies when the radio frequency (RF) bursts have a channel length or channel delay spread that can affect receiver performance. The channel length estimation module may disable interference cancellation in response to such a channel length or channel delay spread. Additionally, the channel length estimation module may adjust the number of equalizer states for the single-branch or first branch of a multi-branch equalizer based the channel length or channel delay spread. The multi-branch equalizer improves the signal-to-noise ratio by improving the equalization by selectively disabling interference cancellation and adjusting the number of equalizer states for the single-branch or first branch equalizer.

摘要： A Space Time Transmit Diversity (STTD) Decoder includes a physical channel despreader, a delay buffer, an upper processing branch, a lower processing branch and a combiner. The upper processing branch is operable to apply a conjugate of a first channel estimate to the delay buffer symbol output and produce non STTD encoded symbols. The lower processing branch is operable to read delayed delay buffer symbol outputs and apply a conjugate of a second channel estimate when active in the STTD mode. The lower processing branch then may apply an STTD decoder scheme to the delay buffer symbol output to produce non STTD encoded symbols. The combiner then combines the non STTD encoded symbols of the upper processing branch and non STTD encoded symbols of the lower processing branch to produce a single set of non STTD encoded symbols.

摘要： An HSDPA rake receiver has a plurality of rake fingers. Different channels may experience different spreading factors. The channel estimate (CE) and the CE delay may be affected and depend on the spreading factor. The CE delay is related to the individual rake finger output buffer size. According to the structure of the present invention, an adaptive channel estimate delay that depends on the spreading factor may result in improved performance.
