Abstract: A method for compensating for a sampling clock-offset includes calculating a positive threshold and a negative threshold of pulse-shaped data symbols to be received, calculating a positive sum ratio and a negative sum ratio from received samples, and compensating for a sampling clock-offset in response to the positive sum ratio being less than or equal to the positive threshold and the negative sum ratio being less than or equal to the negative threshold.

Abstract: 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.

Abstract: A method and a transmitter for transmitting a pay load sequence are provided. The transmitter includes a ternary sequence mapper configured to map a binary data sequence to a ternary sequence stored in the transmitter, and a pulse shaping filter configured to generate a first signal based on the mapped ternary sequence. The ternary sequence includes elements of −1, 0, and 1.

Abstract: A method to compensate a carrier frequency offset (CFO) in a receiver is disclosed. The method includes receiving discrete time samples, obtaining a sample vector from the received discrete time samples, obtaining tentative CFO estimates based on the sample vector, selecting a CFO having a greatest compensation coefficient from the tentative CFO estimates, and compensating the CFO in the received discrete time samples.

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.
