摘要： A method for synchronizing communications between first and second piconets is provided. It is determined whether superframes corresponding to the first and second piconets are synchronized according to respective beacon period start times from the detected beacons. When the superframes are not synchronized, a type of overlap is determined. The type of overlap includes 1) an overlap between beacon periods, 2) an overlap between reservation periods and 3) an overlap between beacon periods and reservation periods of the superframes. The first and second piconets are merged into a single piconet according to rules based on the determined type of overlap.

摘要： Method and computer program products for enhancing wireless communication in a wireless network are disclosed. In the wireless network, frames of data are transmitted in bursts. Wireless communication is enhanced by transmitting a first frame of source data that is scrambled using a scrambling sequence in a first burst, storing an indicator corresponding to the scrambling sequence for the first frame, identifying the scrambling sequence of the first frame for retransmission of the first frame, retransmitting the first frame (which is scrambled using the identified scrambling sequence) in a subsequent burst, receiving the trasmitted and retransmitted first frames, and processing the received transmitted and retransmitted first frames to recover the source data.

摘要： Scrambling methods for scrambling ultra wideband (UWB) data are disclosed. UWB data (420) having payload data and non-payload data is scrambled (422, 424) by shifting a first bit string (412) a first number of bits, shifting a second bit string (410) a second number of bits, combining (414A - 414N) the first and second shifted bit strings, generating (418) scrambler control bits (416) from the combined first and second shifted bit strings, and scrambling (424) at least a portion of the UWB data responsive to the scrambler control bits. According to another aspect, UWB data is scrambled by scrambling payload data using a pseudo-random number generator having a seed set of multiple seeds having low seed correlation, each seed within the seed set having a predefined number of bits, and selective applying random frame reversion (428, 430) to non-payload data and/or to entire frame of data.

摘要： A control method of synchronizing communications between or among a plurality of devices in a communication system includes detecting beacons from the devices in the communication system and establishing a reservation for at least a portion of the devices in the communication system. Each reservation is a frame interval in which to transmit symbols from one device to other devices in the communications system. Each frame interval and inter-frame interval may be set according to the established reservation. Each frame interval and inter-frame interval may be a plural, integral number of symbol periods in duration. Each device may determine a time-frequency code (TFC) for each of the other devices in the communication system according to the detected beacons from the other devices and may adjust a frequency band for transmission according to the determined TFC to transmit one or more symbols from the respective device using the adjusted frequency band.
