Abstract: A mobile device is provided. The mobile device includes a transceiver, a sensor unit, a storage device and a processor. The sensor unit detects the position and the motion of the mobile device to provide sensor data. The storage device stores activity records. The processor obtains an identification code of the base station connected to the mobile device through the transceiver and calculates the height of the mobile device according to the sensor data. When the identification code of the base station and the height of the mobile device match those in an activity record, the processor executes a predetermined function corresponding to the activity record. When the execution of the predetermined function fails, the processor generates a moving trail of the mobile device according to the sensor data. When the moving trail of the mobile device matches that in the activity record, the processor executes the predetermined function.

Abstract: For some applications such as high-speed communication over short-reach links, the complexity and associated high latency provided by existing modulators may be unsuitable. According to an aspect, the present disclosure provides a modulator that can reduce latency for applications such as 40G/100G communication over copper cables or SMF. The modulator has a symbol mapper for mapping a bit stream into symbols, and a multi-level encoder including an inner encoder and an outer encoder for encoding only a portion of the bit stream. In some implementations, the multi-level encoder is configured such that an information block size of the inner encoder is small and matches a field size of the outer encoder. Therefore, components that would be used to accommodate larger block sizes can be omitted. The effect is that complexity and latency can be reduced. According to another aspect, the present disclosure provides a demodulator that is complementary to the modulator.

Abstract: In order to generate multiple-access signals, each transmitter transmits information by using all or a part of channel resources. The signal of each transmitter is mapped to an OFDM time-frequency resource space as a trellis modulation path. A mobile communication system maps trellis modulation paths of a plurality of transmitters to the same resource space. In order to effectively detect and distinguish signals of a plurality of transmitters transmitted through the same channel resource space, a receiver uses a message passing method between symbols and a path connection method. The receiver uses a state space expansion method, a backward pre-decoding method, and a successive interference cancellation method to more efficiently reconstruct a discovery signal.
