Abstract: A method for radio frequency (RF) pulse synchronization in a super regenerative receiver (SRR), includes receiving an input signal including an asymmetric preamble, and estimating a phase difference between the input signal and a quench signal based on the asymmetric preamble. The method further includes compensating for the phase difference.

Abstract: A device is adapted for use in a body area network capable of low power communications wherein a number of piconets can operate within close proximity. The device is configured to couple to a plurality of secondary devices in a piconet. The device uses an interference mitigation technique to enable the devices in the piconet to use the same frequency and same time as a number of adjacent piconets located in close proximity to the piconet. The interference mitigation technique is at least one of a low duty cycling operation; and a preamble sequence designed to operate under interference.

Abstract: The present invention provides an ultra-wide band (UWB) system and method. In one embodiment, a transmitter of a low duty cycled ultra wide band (UWB) system includes a differential spreading encoder for encoding a phase of a bit sequence based on a reference bit sequence. The transmitter also includes a pulse generator for generating a number of pulses associated the bit sequence using the encoded phase of the bit sequence, where the number of pulses is equal to a length of the bit sequence. Moreover, the transmitter includes a DMPSK modulator for generating a modulated signal through modulating the number of pulses using a phase of a differential data symbol.

Abstract: A method and system for managing a body area network using a coordinator device. The method includes acquiring a medical implant communication service (MICS) channel by an MICS transceiver in the coordinator device. The method also includes sending a signal, indicative of a wake-up process, in a non-MICS channel to an implant device and a command signal, indicative of joining a piconet, by the MICS transceiver to an implant device. Further, the method also includes receiving an acknowledgement signal by the MICS transceiver of the coordinator device based on the sending of the command signal to the implant device. The acknowledgement signal comprises a security control field. Furthermore, the method includes initiating security procedures based on the security control field. Further, the method also includes exchanging data between the coordinator device and the implant device based on the initiating and disassociating the implant device by sending a command message.

Abstract: Disclosed is a phase noise compensation apparatus to be applied to the OFDM system, comprising an ICI estimating unit for estimating inter carrier interference (ICI) using a pilot sub-carrier included in a reception signal, a estimating unit for estimating a common phase error (CPE), which is a phase noise from the reception signal as sampled, using the pilot sub-carrier, and estimating a transmission signal by removing the estimated CPE from the reception signal, a calculating unit for calculating phase change by the ICI in the reception signal by convoluting the ICI and the transmission signal, and an equalizer for compensating the calculated phase change by the ICI in the reception signal. Accordingly, phase noise can be exactly compensated by estimating as phase noise the result of convoluting a received signal where the CPE is removed in a frequency domain and the estimated ICI according to the present invention.
