    摘要: The present teaching relates to collecting and processing location-specific wireless waveforms for use in wireless communication, components, methods, apparatuses, servers, and systems. In one embodiment, a disclosed system comprises a first wireless transceiver of a first device, and at least one second wireless transceiver of at least one second device. The first wireless transceiver of the first device is wirelessly coupled to the at least one second wireless transceiver through a wireless multipath channel associated with a space. The first device with the first wireless transceiver comprises a processor and a memory, which are configured to obtain a set of channel information (CI) and perform a task associated with the space based on the set of channel information. The set of channel information is captured when at least one probing signal is either (1) sent from the first wireless transceiver to a particular second wireless transceiver through the wireless multipath channel associated with the space, or (2) sent from the particular second wireless transceiver to the first wireless transceiver through the wireless multipath channel. The set of CI comprises a channel impulse response, a channel frequency response, a channel profile, and/or another channel data of the wireless multipath channel.

    摘要: A binaural cochlear implant system (system) includes first and second microphones associated with first and second ears of a patient, respectively. The microphones detect an audio signal presented to the patient and output first and second signals representative of the audio signal as detected at the first and second ears, respectively. The system also includes a first sound processor that receives the first signal from the first microphone and the second signal from a second sound processor by way of a communiation link with the second sound processors. The first sound processor generates first and second fine structure signals representative of fine structure information of the first and second fine structure signals, respectively, and generates a timing pulse signal based on the first and second fine structure signals. The first sound processor uses the timing pulse signal to represent to the patient an interaural time difference between the first and second signals.

    摘要: The present invention discloses a channel reconstruction method for a downlink multi-antenna-multi-base-station with inconsistent antenna configuration. Firstly, a serving base station configures a user equipment. If antenna configuration of the multi-antenna-multi-base-station system is inconsistent, virtual antennas are introduced to a base station with fewer antennas in the system. A user equipment selects and feeds back indices of the virtual antennas and reconstructs channels of the multi-antenna-multi-base-station system to generate a consistent antenna configuration. Finally, the multi-antenna-multi-base-station system transmits a signal to the user equipment by adopting a transmission pre-processing scheme of the consistent antenna configuration. The present invention provides also a serving base station, a cooperative base station and a user equipment for realizing the channel reconstruction method. The present invention has advantages of large application range, simple implementation and better performance.
