    Abstract: Demodulation and interference parameter estimation m an OFDM receiver is improved by identifying regions, in a two-dimensional arras of time-frequency transmission positions, having related interference parameters, such as resulting from the same pre-coding scheme, transmission rank, transmitting antennas, and the like. An interference measure is estimated for each of a plurality of time-frequency positions. The interference measures are analyzed by considering them as pixels, or picture elements, in a two-dimensional image, and applying image processing algorithm to identify the regions having related interference parameters The image processing algorithms may include operations such as edge detection, segmentation, and or clustering The receiver may perform interference suppression or cancellation such as interference rejection combining of data extracted from signals received within an identified time-frequency region having related interference parameters.

    Abstract: A receiver includes a receiver circuit that decodes multiple signals of interest contained in a composite receive signal. The receiver comprises at least one Generalized RAKE combining circuit and a joint demodulation circuit and generates a detected signal at an output. The joint demodulation circuit contains a reduced search soft value generator circuit and generates soft bit values that represent coded bits received from the transmitter.

    Abstract: A mobile terminal measures interference over multiple measurement periods and generates interference probability data based on the statistical distribution of the interference measured. The interference probability data may describe, for example, the probability of each possible level of interference expected at the mobile terminal. The mobile terminal derives channel quality information as feedback to a base station based on this interference probability data (e g., when noise at the mobile terminal falls below a threshold) Ln one embodiment the mobile terminal does so by estimating from the interference probability data the probability of success folly receiving a transmission if certain feedback information is reported. Derived in this way, the feedback information more reliably indicates interference likely present at the mobile terminal when the base station sends the transmission. Accordingly, the base station controls the transmission based on the feedback information, and in some embodiments, also based on the interference probability data.
