    Abstract: A method and apparatus for a collision-free carrier sense multiple access (CSMA) are provided. The method of a node associated with a beacon enabled carrier sense multiple access (CSMA)-based wireless communication network through an access point (AP) includes receiving a beacon from the AP, the beacon comprising a back-off prime number and a beacon random number, and generating a back-off interval based on the beacon random number, the back-off prime number, a mapped identification (ID) of the node, and a current time slot of a frame of the beacon. The method and apparatus provide a collision-free CSMA scheme for a beacon enabled CSMA-based wireless communication network. In the collision-free CSMA scheme, uniformly distributed back-off intervals may be generated in a distributed fashion at each node for a CSMA-based wireless communication network. The back-off intervals may be correlated among the nodes even though the nodes do not communicate with each other.

    Abstract: The present invention describes a method and system for simultaneous transmission of data to coherent and non-coherent receivers. The method at the transmitter includes retrieving a base ternary sequence having a pre-defined length, obtaining one or more ternary sequences corresponding to data to be transmitted and transmitting the obtained one or more ternary sequences by the transmitter. The method steps at the receiver includes receiving one or more ternary sequences corresponding to the data transmitted, demodulating each of the received ternary sequences by correlating with all cyclic shifts of the base ternary sequence by the receiver if the receiver is a coherent receiver, demodulating each of the received ternary sequences by correlating with all cyclic shifts of the absolute of the base ternary sequence by the receiver if the receiver is a non-coherent receiver and detecting the transmitted data based on the cyclic shifts corresponding to maximum correlation values.

    Abstract: Provided is a method of estimating a Direct Current (DC) offset in an Ultra-Low Power (ULP) receiver. The method includes receiving a signal from an output of an Analog to Digital Converter (ADC) in the ULP receiver. The signal includes a correlated variable DC component for at least one of an in-phase arm and a quadrature arm of the ULP receiver. The method also includes estimating a DC offset compensation parameter in a plurality of phases for a plurality of stages based on the received signal such that the estimating includes calculating the DC offset compensation parameter in a magnitude estimation phase for the plurality of stages and calculating the DC offset compensation parameter in a sign estimation phase for the plurality of stages.
