Abstract: A method and an apparatus for controlling an interleaving depth are provided. The interleaving depth controlling method includes performing a modulo operation on an interleaving depth selected to be less than or equal to a maximum interleaving depth and a total number of codewords to obtain a number of remaining codewords; and comparing the total number of the codewords to the interleaving depth, when the number of the remaining codewords excludes “0”, to control the interleaving depth.

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 device for transmitting a preamble sequence is disclosed. A transmitter according to an embodiment may extract a first sequence for a non-coherent receiver and a second sequence for a coherent receiver, from ternary preamble sequences including elements −1, 0 and 1, and map the first sequence and the second sequence to a preamble including a plurality of bits to generate a third sequence that the non-coherent receiver and coherent receiver support.

Abstract: Embodiments herein achieve a method and system for selecting non-coherent spreading sequences with binary alphabets {0, 1} with variable spreading factors. The method generates circular shift equivalent sets of spreading sequences by circularly shifting base sequences with elements {1, 0} and having at least one variable spreading factor. The method determines whether each spreading sequence in the circular shift equivalent set meets pre-defined spreading sequence criteria. The spreading sequence criteria comprise balanced criteria, a non- repetition criteria, non-circular criteria, and conjugate criteria. Furthermore, the method selects the spreading sequence from expansions of at least one spreading sequence from the circular shift equivalent sets in response to determining that the spreading sequences in the circular shift equivalent sets meets the pre-defined spreading sequence criteria.

Abstract: A method and an apparatus for gesture recognition and a wearable device for gesture recognition are described. A method of gesture recognition involves using a processor to detect a motion artifact from an output signal of a biosignal sensor and generating a control signal to control a function of a target device that corresponds to a reference signal pattern in response to a signal pattern of the detected motion artifact corresponding to the reference signal pattern.
