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: Disclosed is a method and apparatus to detect an intended packet by a sliding intermediate frequency (SIF) coherent ultra low power (ULP) wireless receiver. The method includes detecting a transition from a noise period to a signal period in a pair of input sequences received, dynamically adjusting a gain of the pair of input sequences in response to the signal period being initiated, distinguishing an intended packet from packets received in preambles included in the pair of input sequences, and compensating for a carrier frequency offset of the intended packet in the signal period.
