Disclosed is a method and system to transmit independent data by at least two transmitters to corresponding at least two receivers. The method includes obtaining, at a first transmitter, a first ternary sequence from a first base ternary sequence corresponding to a first set of data-symbols, and obtaining, at a second transmitter, a second ternary sequence from a second base ternary sequence corresponding to a second set of data-symbols. The method also includes transmitting, from the first transmitter, the first ternary sequence to a first set of receivers associated with the first transmitter. The method transmits, from the second transmitter, the second ternary sequence to a second set of receivers associated with the second transmitter.

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.

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.
