  • Low peak to average ratio search algorithm
    Publication number: 20050237921
    Abstract: The present invention provides a method for selecting channel estimation sequences with low Peak to Average Ratios (PAR) for Orthogonal Frequency Division Multiplexing (OFDM) signals. The method involves selecting a channel estimation sequence and random and then searching all sequences within a defined neighborhood (distance) of that sequence. If any of the sequences in the neighborhood have a PAR lower than the seed sequence, that new neighborhood sequence becomes the new seed, and the algorithm now searches all sequences within a defined distance of the new seed to determine if any of them have a lower PAR. This process is repeated until the process converges on the sequence with the lowest PAR.

  • Low peak-to-average ratio preamble, and associated method, for packet radio communication system
    Publication number: 20050195906
    Abstract: Apparatus, and an associated method, for facilitating communications is a packet radio communication system, such as an IEEE 802.15.3a-compliant communication system. A deterministic sequence is used as a channel estimation sequence. The channel estimation sequence exhibits a peak-to-average ratio of lower than 8.86 dB.
