摘要： A transceiver for providing full-duplex communications includes a multilevel patch antenna array having a first patch antenna array for transmitting the first carrier signal on the first channel including a first plurality of patch antennas thereon and a second patch antenna array for receiving the second carrier signal on the second channel including a second plurality of patch antennas thereon. Transmitter circuitry associated with the first patch antenna array transmits first signals having a first orthogonal function applied thereto on a first channel on a first frequency band. Receiver circuitry associated with the second patch antenna array receives remotely transmitted second signals on a second channel on the first frequency band having a second orthogonal function applied thereto and the first signals transmitted from the first patch antenna array having the first orthogonal function applied thereto on the first channel on the first frequency band at a same time on the first frequency band. The receiver circuitry only processes received signals including the second orthogonal function. The first orthogonal function applied to the first signals transmitted from the first antenna array and the second orthogonal function applied to the second signals prevents interference between the first signals and the second signals that are being simultaneously transmitted and received on the first frequency band at the multilevel patch antenna array.

摘要： A technique for cancelling inter-cell or intra-cell interference in a cellular communication network is described. A method implementation of that technique performed in an interfered terminal comprises receiving a signal, wherein the received signal comprises an interfering signal destined to at least one further terminal different from the interfered terminal. In a next step, control information pertaining to the at least one further terminal is determined and the interfering signal is decoded based on the control information so as to generate decoded information. Then, the interfering signal is re-generated from the decoded information and the control information. Based on the re-generated signal the interfering signal is cancelled from the received signal.

摘要： An apparatus, system, and method are provided for reducing a number of intersymbol interference components to be suppressed. Included is a receiver path with a linear equalizer configured to: receive a signal pulse including a data component and a first number of post-cursor intersymbol interference components, delay and process the signal pulse such that the signal pulse includes a second number of post-cursor intersymbol interference components which is less than the first number of post-cursor intersymbol interference components, and produce an output signal that includes the data component and the second number of post-cursor intersymbol interference components. The receiver path further includes a decision feedback equalizer in electrical communication with the linear equalizer. The decision feedback equalizer is configured to: receive the output signal from the linear equalizer, and suppress the second number of the post-cursor intersymbol interference components of the output signal.

摘要： An impulsive noise detection method is applied to an orthogonal frequency-division multiplexing (OFDM) system to detect whether an input signal includes impulsive noise. The impulsive noise detection method includes receiving the input signal, converting the input signal to a digital input signal, filtering out a data band from the digital input signal to generate a signal under detection, calculating the signal under detection to generate a calculation result, and determining whether the input signal includes the impulsive noise according to the calculation result and a threshold.

摘要： The present invention relates to a method of transmitting and receiving a signal in a wireless communication system. In particular, in a time division multi-cell cooperative communication system, a base station may receive a reference signal, estimate a channel of each user terminal based on the reference signal, and determine a transmission and reception filter based on estimated channel information. The base station and a cooperative base station that cooperates with the base station may mutually exchange the reference signal and average signal power information on a terminal and determine the transmission and reception filter based on exchanged information.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a neighbor cell and report the result to a serving base station. Based on the report, the serving base station may identify an estimated discovery reference signal (DRS) transmission window of the neighbor cell. In some cases, the UE may estimate and report parameters of the neighbor DRS transmission window, and in other cases, the UE may make a measurement report and the base station may infer DRS transmission window parameters. The base station may then provide the UE with a DRS measurement timing configuration (DMTC) based on the estimated parameters of the neighbor cell so that the UE may monitor the neighbor cell and the serving cell in an efficient manner. For example, the UE may conserve battery life by refraining from monitoring DRS during periods when a DRS transmission is not likely.
