Described herein is the generation of a signal for an analysis of a communication network based on a first version of a radio signal transmitted from a first node of the radio communication system to a second node of the radio communication system received at a passive node by detecting deviations of the first version of the transmitted radio signal from a second version of the radio signal received at the second node, and generating the signal based on the deviations.

Apparatuses and methods related to digital mobile radio (DMR) with enhanced transceiver are disclosed herein. The transceiver detects waveforms of signals received by a digital mobile station radio (MS). By detecting whether the waveforms of the signals, the transceiver allows a digital baseband processor of the MS to remain in a sleep state while the signals are being detected by the DMR, thereby reducing an amount of power used while the signals are being detected.

This application relates to the field of communication technologies, and discloses a communication method and apparatus. On example method includes: a backscatter device receives an excitation signal from an exciter. The backscatter device determines a backscatter signal pattern in a backscatter signal pattern set, where the backscatter signal pattern set includes a plurality of backscatter signal patterns, and backscatter reference signals in the plurality of backscatter signal patterns do not overlap in time domain. The backscatter device modulates a backscatter reference signal and a backscatter data signal on the excitation signal based on the determined backscatter signal pattern, to obtain a backscatter signal. The backscatter device sends the backscatter signal to a receiver.

A method of transmitting a Physical Layer Convergence Procedure (PLCP) frame in a Very High Throughput (VHT) Wireless Local Area Network (WLAN) system includes generating a MAC Protocol Data Unit (MPDU) to be transmitted to a destination station (STA), generating a PLCP Protocol Data Unit (PPDU) by adding a PLCP header, including an L-SIG field containing control information for a legacy STA and a VHT-SIG field containing control information for a VHT STA, to the MPDU, and transmitting the PPDU to the destination STA. A constellation applied to some of Orthogonal Frequency Division Multiplex (OFDM) symbols of the VHT-SIG field is obtained by rotating a constellation applied to an OFDM symbol of the L-SIG field.

A receiver, including: a sampling circuit configured to convert a received analog signal into a digital signal; a variance determination circuit configured to determine a phase difference variance of the digital signal; and a frequency shift keying (FSK) discrimination circuit configured to discriminate, based on the phase difference variance, whether the received analog signal is an FSK-modulated signal.
