摘要： A method for successive interference cancellation in code division multiple access (CDMA) systems is provided that uses variable interferer weights. This method allows interfering signals to be cancelled in order to recover a transmitted data signal. This method involves receiving the data signal subject to interference from at least one interfering signal. A first interfering signal is identified. Then an interferer weight coefficient associated with the first interfering signal is generated. This allows the first interfering signal to be cancelled from the received data signal using the interferer weight coefficient. These processes may then be reiterated for other interfering signals. It is then possible to recover the transmitted data signal from the received data signal.

摘要： A method having enhanced decoding operations associated with receiving multiple Radio Frequency (RF) Burst(s) is provided. Multiple RF burst(s) are received where the multiple RF Burst(s) include first RF bursts and second RF Burst(s). The second RF bursts may be transmitted in parallel or in response to a decoding error associated with the first RF burst. The received RF burst(s) are equalized and deinterleaved to yield extracted soft samples. Then the first estimated bit sequences and second estimated bit sequences are decoded from the extracted soft samples. A set of possible bit sequences may then be pruned based on based on combined knowledge of the first estimated bit sequence and the second estimated bit sequences. This pruned set may be compared using a sequence detector and the combined first estimated bit sequences and second estimated bit sequences to select a decoded bit sequence. This allows a sequence detector to use a combination of the original decoded data and the reordered decoded data as constraints when applying a turbo code technique to decode the data. The combination of the original coded data and reordered coded data results in a performance enhancement by providing further constraints.

摘要： This invention provides colored noise detection algorithm(s). This colored noise detection algorithm(s) may be implemented with a multi-branch equalizer processing module that enables interference cancellation when colored noise is associated with received radio frequency (RF) bursts. The noise discriminator identifies when the radio frequency (RF) bursts have white noise or colored noise associated with them. Alternatively the noise discriminator may be able to determine and enable interference cancellation in response to an interference-limited received RF burst as opposed to a noise-limited received RF burst. The multi-branch equalizer improves the signal-to-noise ratio by improving the equalization with a second branch operable to be trained based upon known training sequences and at least partially re-encoded data bits.

摘要： The present invention provides a multi-branch equalizer processing module operable to cancel interference associated with received radio frequency (RF) burst(s). This multi-branch equalizer processing module includes both a first equalizer processing branch and a second equalizer processing branch. The first equalizer processing branch is operable to be trained based upon known training sequences and equalize the received RF burst. This results in soft samples or decisions which in turn may be converted to data bits. The soft samples are processed with a de-interleaver and channel decoder, where the combination is operable to produce a decoded frame of data bits from the soft samples. A re-encoder may re-encode the decoded frame to produce re-encoded or at least partially re-encoded data bits. An interleaver then processes the at least partially re-encoded data bits to produce and at least partially re-encoded burst. The second equalizer processing branch uses the at least partially re-encoded data bits to train linear equalizer(s) within-the second equalizer processing branch. A buffer may initially store the received RF burst(s), which are retrieved and equalized by the second equalizer processing branch once the linear equalizer(s) are trained. This results in alternate soft samples or decisions which in turn may be converted to alternate data bits. The alternate soft samples are processed with the de-interleaver and channel decoder, where the combination is operable to produce an alternate decoded frame of data bits from the alternate soft samples. This allows interfering signals to be cancelled and more accurate processing of the received RF bursts to occur.

摘要： A method of chip interleaving in direct sequence spread spectrum communications. A binary code sequence is chosen to have a length N=2k−1 and to be self-orthogonal. A data string of M=QN+1 bits, QN−1 bits, or QN+S bits, where Q is a positive integer and S is an integer between 1 and N that lacks a common factor with N, is multiplied sequentially with the binary code sequence until N chip frames of M chips each are produced. These chip frames are transmitted to a receiver, and recovered in an equally straightforward manner. The integers Q and N are chosen according to transmission conditions.

摘要： A method and system for improving reception in wired and wireless systems through redundancy and iterative processing are provided. A multilayer decoding process may comprise a burst process and a frame process. Results from a first burst process may be utilized to generate a decoded bit sequence in the frame process. The frame process may utilize redundancy information and physical constraints to improve the performance of a decoding algorithm. Results from the frame process may be fed back for a second iteration of the burst process and of the frame process, to further improve the decoding operation. In some instances, the second iteration of the burst process may be based on a gradient search approach.
