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 transmitter is configured to transmit a radio frequency (RF) signal to a receiver. The receiver is configured to receive the RF signal and decode data. Furthermore, a method of wireless communication is provided between the transmitter and the receiver, in which the transmitter transmits to the receiver the RF signal. A carrier phase of the RF signal is randomly converted. The receiver detects an envelope of the RF signal, and extracts data from the RF signal.
Abstract:
Examples provide a method of performing automatic gain control (AGC) in a wireless receiver, the method including computing, by an energy detection (ED) circuit, a variance in an output signal of an analog-to-digital converter (ADC), and activating, by the ED circuit, an AGC circuit to adjust a gain of at least one component in a radio frequency integrated chip (RFIC) in response to the variance exceeding a threshold. Examples also provide for a wireless receiver that implements such a method.
Abstract:
Provided is a method and apparatus to adaptively set a threshold for signal demodulation. The apparatus and the method include adaptively setting a threshold to demodulate a currently received symbol based on the demodulation value of a previously received symbol based on a comparison value. The comparison value is obtained by comparing a number of previously received symbols having a demodulation value of “0” and a number of currently received symbols having a demodulation value of “1”.
Abstract:
A method of detecting a bit sequence, includes estimating parameters to be used to determine a probability distribution of a present signal in each of states of a present time, and calculating metrics of the respective states based on the parameters. The method further includes selecting survivor states from the states based on the metrics, and detecting the bit sequence based on a path to each of the survivor states.
