摘要： A method of constructing a puncture sequence includes providing a seed puncture sequence including a plurality of elements. The elements of the seed puncture sequence are based upon non-zero elements of a plurality of columns of a parity-check matrix having a column dimension and a row dimension. In this regard, the parity-check matrix defines an error correction code, and has been constructed based upon a seed parity-check matrix derived from an edge ensemble. After providing the seed puncture sequence, a variable node-puncture sequence can be constructed based thereupon. The variable node-puncture sequence, then, corresponds to a puncture sequence configured for processing an error correction code.

摘要： A method of adaptive error correction coding includes processing data during a connection between a transmitting entity and a receiving entity, where the data is processed in accordance with a predetermined coding scheme. More particularly, processing data includes encoding one or more sequences received by an error correction encoder of the transmitting entity, or decoding one or more block codes received by an error correction decoder of the receiving entity. During the connection, then, the method includes selecting or receiving a selection of feedback code information. Thus, during at least a portion of the connection, the data processing is switched to processing data in accordance with a parity-check coding technique based upon the feedback code information.

摘要： In one aspect thereof this invention provides a method to increase data throughput in an Orthogonal Frequency Division Multiplex (OFDM) wireless communications system. The method includes modeling data throughput as a function of received Signal to Noise Ratio (SNR) with a sigmoid function to produce a throughput curve characterized as having a lower knee region and an upper knee region; and performing a gradient ascent search along the throughput curve by varying the power of a plurality of sub-carriers so as to remove power from any sub-carrier having a received SNR to the left of the lower knee region, and to re-allocate the removed power to sub-carriers having a received SNR to the right of the lower knee region.

摘要： Fast fading in cellular systems causes time variation of the Channel Impulse Response (CIR) resulting in significant performance degradation that is reduced by adding a pulse train to the transmitted data symbols and estimating the CIR by averaging the symbols as they vary from one OFDM symbol to another within the physical data frame (or packet).

摘要： Apparatus, and an associated method, for facilitating optimization of the communication capacity of a communication system. A selector is coupled to receive channel state information associated with the channel conditions upon subcarriers defined pursuant to an OFDM (orthogonal frequency division multiplexing) the selector operates to select communication allocation of the data to be communicated on the different ones of the subcarriers. Selection is made pursuant to a selected optimization scheme. And, bit and power profiles are formed that are utilized to control the modulation scheme by which data is modulated upon the different subcarriers. As channel conditions change, the communication allocations are adaptively altered.
