    摘要: A first wireless device communicates data to a second wireless device. The first wireless device employs at least one of a first interleaving scheme and a first sub-carrier mapping scheme to produce a first data packet from a first plurality of data bits, and transmits the first data packet to the second wireless device. When the first data packet is not received correctly by the second wireless device, then the first wireless device employs at least one of a second interleaving scheme and a second sub-carrier mapping scheme to create a second data packet from the first plurality of data bits, and transmits the second data packet to the second wireless device.

    摘要: A medical system includes one or more MBAN devices which acquire and communicate patient data. One or more medical body area network (MBAN) systems include the one or more MBAN devices communicating the patient data with a hub device via short-range wireless communication. The communication of the patient data via the short-range wireless communication being within a predefined spectrum. The hub device receives patient data communicated from the one or more MBAN devices, communicates with a central monitoring station via a longer range communication and one or more access points (AP), and determines the location of the MBAN system in reference to a healthcare facility. The one or more MBAN devices are inhibited from transmitting within the predefined spectrum when the MBAN hub device is located outside the healthcare facility.

    摘要: A wireless bit-interleaved coded OFDM (BI-COFDM) multiple-in-multiple-out (MIMO) system that improves the diversity seen by a convolutional decoder. The bit stream is interleaved first, then bits are mapped into symbols and then symbols are parsed into Nt separate streams, where t is the number of transmitters. A deinterleaver then performs the inverse permutation before sending the symbols to a Viturbi decoder. In another embodiment, a transmitting side bit-interleaver transforms an encoded and punctured bit stream using a first permutation, groups the transformed bit stream according to a desired constellation on one of Nt antennae, splits the transformed bit stream into separate streams accordingly and bit-interleaves/symbol-maps using a plurality of bit-interleavers/symbol-mappers to permute each stream using a second permutation. A receiving side performs the inverse operations of the transmitting side.

    摘要: A system includes a first primary wireless system (120) that communicates over a first range, and a first beaconing device (130) associated with the first primary wireless system (120). The first beaconing device (130) communicates over at least at a second range, wherein the second range is greater than the first range. The first beaconing device listens for beacons (510) from other beaconing devices (130) associated with other primary wireless systems (120) on a plurality of channels over which the other primary systems may operate. After listening for beacons from the other beaconing devices (130) associated with other primary wireless systems, the first beaconing device transmits a first beacon (510) to a wireless device (114) of a secondary wireless system (110) that may communicate over the second range. The first beacon includes data indicating an occupation of a first one of the channels by the first primary wireless system (120).
