A method compensates for a frequency error in a communications system. The method includes detecting a received preamble sequence in a received signal. The received preamble sequence is detected based on a plurality of power estimates corresponding to a plurality of frequency bins of a received frequency domain signal and a plurality of relative phase errors corresponding to the plurality of frequency bins of the received frequency domain signal. The method includes determining the frequency error using the received preamble sequence. The method includes adjusting the receiver based on the frequency error.

A method and apparatus for wireless communication in a wireless personal area network (WPAN) communication system. A wireless communication method to be performed by a first wireless communication device includes broadcasting a beacon, receiving an association request signal from a second wireless communication device receiving the beacon, and performing association with the second wireless communication device after receiving the association request signal, in which the first wireless communication device may suspend beacon transmission after the association with the second wireless communication device is established.

An ultra-wideband communication and/or location system having a plurality of channels, each implementing a respective one of a plurality of predetermined codewords. Within each channel, one or more predetermined pulse repetition frequences are defined. Within a single UWB system, more than two networks of transceivers may be co-located without mutual interference if each is assigned a unique combination of codewords and spreading factors.

An electronic device that communicates with a second electronic device using adaptive frequency hopping across different spectral bands is described. An integrated circuit in the electronic device includes processing logic that determines an adaptive spectral map that specifies channels across multiple spectral bands. During communication with a second electronic device that includes a second integrated circuit using a communication protocol (such as Bluetooth or Bluetooth Low Energy), the integrated circuit selects channels in the adaptive spectral map, where selection can be based on a predefined frequency-hopping sequence.
