Abstract:
A method of timing synchronization in sub-band based ultra wideband systems, includes obtaining a coarse estimate of an offset in a time domain at a sub-sampled rate, and obtaining a fine estimate of the offset in an analog domain. The method further includes correcting a timing in the analog domain by transforming the fine estimate to an equivalent phase for the correcting.
Abstract:
A method of per-tone spreading in single carrier block transmissions, includes generating a block of modulated symbols, and performing the per-tone spreading on the block of the modulated symbols. Also, a transmitter configured to perform per-tone spreading in single carrier block transmissions, includes a modulator configured to generate a block of modulated symbols, and a spreader configured to perform the per-tone spreading on the block of the modulated symbols.
Abstract:
A method and an electronic device for establishing, at a first electronic device, a communication link between the first electronic device and at least one other electronic device in a Near Field Communication (NFC) network are provided. The method includes setting up an underlying Media Access Control (MAC) link; sending a Parameter Exchange (PAX) command for exchanging parameters concerning a Logical Link Control Protocol (LLCP) to at least one other electronic device; receiving a response PAX command for exchanging parameters concerning the LLCP from at least one other electronic device; and establishing the communication link between the first electronic device and the at least one other electronic device based on the received response PAX command.
Abstract:
A method and an electronic device for establishing, at a first electronic device, a communication link between the first electronic device and at least one other electronic device in a Near Field Communication (NFC) network are provided. The method includes sending, to the at least one other electronic device, after setting up an underlying Media Access Control (MAC) link between the first electronic device and the at least one other electronic device, a Parameter Exchange (PAX) command for exchanging parameters concerning a Logical Link Control Protocol (LLCP) link to be established with the at least one other electronic device; receiving, a response PAX command for exchanging parameters concerning the LLCP link; and establishing the LLCP link with the at least one other electronic device based on the response PAX command, wherein the PAX command comprises a parameter list of one or more services registered in the first electronic device.
Abstract:
A method and an electronic device are provided for establishing, at a first electronic device, a communication link between the first electronic device and a second electronic device in a Near Field Communication (NFC) network. The method includes sending, to the second electronic device, a discovery request for discovery of one or more services registered in the second electronic device; receiving, from the second electronic device, a discovery response including a parameter list for the one or more services registered in the second electronic device; and establishing a logical link control protocol (LLCP) link between the first electronic device and the second electronic device based on the discovery response. Each of the discovery request and the discovery response is formed in a logical link control (LLC) protocol data unit (PDU).
Abstract:
Apparatus and method for managing connections of a plurality of devices by a Near Field Communication (NFC) Controller (NFCC) through NFC. The method includes setting identification information of an entity, the entity being requested from an NFC device for a connection with the NFC device; and setting a logical link between the NFC device and the entity based on the identification information.
