Abstract: The present invention is directed to optimization and failure detection of a wireless base station network. Based on RF link attenuation measurement, e.g., a Received Signal Strength Indication (RSSI) measurement, a server determines an optimal transmission sequence. Each base station of the optimal transmission sequence, a predecessor and a successor, are designated. Each base station of the sequence generates a packet. Most distant base station (relative to the server) transmits its packet to its successor. Each base station of the sequence (in turn) receives the packet from its predecessor, combines the received packet with its own generated packet, transmits the combined packet to its successor, and so on until the combined packet is relayed to a super base station at the end of the sequence. The super base station transmits the packet to the server. Based on the packet size, server can ascertain which base station (if any) failed.

Abstract: An analog self-interference cancellation technique for In-Band Full-Duplex (IBFD) systems generates an inherent secondary self-interference (SI) signal of a circulator and uses that signal to cancel a primary SI signal leaked from a transmitter port within a communication device. The communication device manipulates the phase and angle of this secondary SI, using an adjustable Impedance Mismatch Terminal (IMT) circuit. The result is an efficient SI cancellation technique in the analog domain, which uses the circulator inherent SI signals.

Abstract: A signal acquisition method and device. Positioning signals as received are divided into at least two groups and frequency compensation is performed on each group of positioning signals. Each frequency compensated group of positioning signals is divided into at least two signal blocks, and an averaging operation is performed on the signal blocks in each group of signals, so as to obtain block-averaged groups of positioning signals. An acquisition result is determined based on the block-averaged groups of positioning signals. Noise power of each block-averaged group of signals is reduced. Therefore, noise power of received positioning signals can be reduced. This may improve signal-to-noise ratio of received signals and acquisition sensitivity of a receiver. Therefore, acquisition success rate of weak signals is increased.
