    摘要: The present invention provides a versatile system for optimizing data fragmentation in a digital communications—particularly OFDM communications—system. A digital transmission system (100) is provided, having a PHY-level constraint. An array (104, 112) of data transmission parameters (106-110, 114-116), relating to the digital transmission system, is provided. A fragmentation construct (102) is provided, and adapted to determine a number of symbols required to transmit a given data transmission payload.

    摘要: A dual mode decoder operable with external memory. At least some of the illustrative embodiments are integrated circuit products comprising a processor portion, a memory portion coupled to the processor portion, and a hardware demodulation portion coupled to the processor portion. The processor portion and hardware demodulation portion work together to demodulate a first digital transmission signal created utilizing a first modulation system, and the processor portion and hardware demodulation portion work together to decode a second digital transmission signal created using a second modulation system different than the first modulation system (the second digital signal having at least one time interleaved segment). The integrated circuit product couples to an external memory for purposes of time de-interleaving when an amount of memory of the memory portion is insufficient for time de-interleaving for a number of segments of the second digital transmission signal.

    摘要: The present invention provides a versatile system for selectively altering or shaping transmission signals in an ultra-wideband communications system (100). The system provides a serial to parallel conversion function (102) with a serial data input (116). The serial to parallel conversion function converts the serial data and outputs it in parallel format. An adjustment function (104) receives the now parallel data and selectively alters the parallel data responsive to some code or vector (118). A frequency-to-time-domain conversion function (106) receives the selectively altered parallel data and transmits it to a parallel-to-serial conversion function 108. The now serial data transfer through an OFDM prefix/suffix function 110 and a digital-to-analog conversion function 112, to an up conversion mixer function 114. Encoded digital data bits are input, converted to parallel format, and passed to the spectrum adjustment function, which provides selective adjustment of specific data units (i.e., specific OFDM sub-carriers or tones).

    摘要: The distance between a first Multi Band Orthogonal Frequency Division Multiplex (MB-OFDM) data transceiver and a second or more such transceiver is determined using known techniques. The radio frequency path loss between transceivers is estimated given said distance, using a known relationship between distance and path loss, and further accounting for line-of-sight or non-line-of-sight conditions if desired. This path loss value is added to the typically minimum transmit power level, absent path loss, needed for reliable data communication. This modified initial transmit power level is then used by the first transceiver to begin the known iterative feedback process of transmit power control (TPC). Because this modified initial transmit power level, based on distance, is closer to the final optimum level, convergence in the TPC process occurs in fewer steps and less time than had the initial transmit power been maximum power as is typical in known TPC systems.
