Abstract: A method to detect a packet includes: receiving an input sequence including preambles; detecting a transition from a noise period to a signal period in the input sequence; dynamically adjusting a gain of the input sequence in response to the signal period being initiated; and distinguishing an intended packet from other packets, among packets received in the preambles.

Abstract: A method and apparatus estimating carrier frequency offset (CFO) with timing synchronization are provided. The apparatus includes processor that receives analog-to-digital converter (ADC) samples, determines a coarse angle from the received ADC samples, obtains an improved coarse angle by altering the coarse angle based on a preamble duration, determines a base CFO estimate from the improved coarse angle and determines a plurality of candidate CFOs based on the base CFO estimate and a difference frequency.

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 of transforming Monte Carlo (MC) simulations for diffuse reflectance spectroscopy (DRS) may include obtaining, by a DRS device, MC simulated DRS measurements using a pre-defined number of photons; pre-processing, by the DRS device, the MC simulated DRS measurements to obtain normalized DRS measurements; correcting, by the DRS device, non-monotonicity of the normalized DRS measurements to obtain monotonic DRS measurements; converting, by the DRS device, the monotonic DRS measurements to a logarithmic domain to obtain logarithmic DRS measurements; performing, by the DRS device, curve fitting on the logarithmic DRS measurements in the logarithmic domain to obtain curve-fitted logarithmic DRS measurements; and transforming, by the DRS device, the curve-fitted logarithmic DRS measurements to a non-logarithmic domain to obtain transformed MC simulated DRS measurements.
