    Abstract: Systems and methodologies are described that facilitate monitoring transmitter performance in a wireless communication environment. If the received modulation symbols are unknown during transmitter monitoring, it may be necessary to determine the modulation symbols for each subcarrier. The modulation types can be evaluated over a subset of subcarriers having a consistent modulation type, to reduce the possibility of an erroneous modulation type determination to an extremely low level. A metric can be generated for each modulation type that indicates the likelihood of a particular modulation type for the subset of subcarriers. The modulation type can be selected based upon the metric and modulation symbols consistent with the modulation type can be used for the subset of subcarriers.

    Abstract: Systems and methodologies are described that facilitate monitoring transmitter performance in a wireless communication environment. A signal analyzer can be used to sample the output of a transmitter and the sampled signal can be propagated to a processor. The processor can generate frequency domain channel estimates for the subcarriers. If the transmitted modulation symbols are unknown, the processor can determine the modulation symbols and use the determined modulation symbols to calculate the channel estimates. The channel estimates can be averaged and used to generate various metrics to evaluate the transmitter performance.

    Abstract: Methods and apparatus for dynamic packet mapping. A method is provided for mapping metric data to produce a decodable packet associated with a channel. The method includes obtaining a channel identifier associated with metric data, determining an available buffer from a plurality of buffers based on the channel identifier, writing the metric data to the available buffer, detecting when a decodable packet is formed in a selected buffer of the plurality of buffers, and outputting the decodable packet from the selected buffer. An apparatus includes a plurality of buffers and mapping logic that is configured to obtain a channel identifier associated with metric data, determine an available buffer based on the channel identifier, write the metric data to the available buffer, detect when a decodable packet is formed in a selected buffer, and output the decodable packet from the selected buffer.

    Abstract: A receiver (106) includes a turbo decoder (124), and a depuncture module (122) configured to enable the turbo decoder to selectively operate at a symmetric code rate (e.g. 1/3 or 1/4) and an asymmetric code rate (e.g. 2/3). The receiver further comprises a LLR module (120) that provides LLR values to the depuncture module. The depuncture module can be realised by means of memory banks (602A, 602B), delays (604A, 604B) and multiplexers (606).

    Abstract: The claimed subject matter relates to estimating noise variance associated with a transmitter. For example, the noise variance can be estimated in connection with determining performance parameters associated with a transmitter. Determining noise variance can include the acts of estimating phase alteration of a received signal through utilization of a least squares-based phase estimation algorithm. Determining noise variance can also include the act of determining an unbiased estimation of noise variance as a function of the estimated phase alteration.
