    摘要: In a communication network, a sending node transmits a message with a multisegment preamble and data to a receiving node. The receiving node calculates characteristics of the sending unit, channel, or transmitted signal by processing preamble segments. Once an unknown characteristic is determined, a segment of the preamble can be eliminated or reduced in length for subsequent messages, which increases efficiency of the message transmissions.

    摘要: In an orthogonal frequency division multiplex (OFDM) communication network, a node transmits an echo profile probe to other nodes in the network. The echo profile probe is a message that allows characterization of the unique echo profile through the communication channel between each node pair. The echo profile is used to calculate the cyclic prefix length needed for optimum communication from one node to the other.

    摘要: Allocations for access in a wireless system may be tiled onto a subframe having a first dimension and a second dimension. In an exemplary embodiment, allocations are distributed along the first dimension while the second dimension is locked, and the allocations are distributed along the second dimension while the first dimension is locked. In another exemplary embodiment, allocations are striped by extending a length of a first allocation along the first dimension and by expanding a breadth of the first allocation along the second dimension responsive to a size of the first allocation and by extending a length of a second allocation along the second dimension and expanding a breadth of the second allocation along the first dimension responsive to a size of the second allocation. In yet another exemplary embodiment, multiple allocations are placed proximately to an allocation placement target and allocation-free areas are produced on a subframe.

    摘要: An endoscopic bite block, with teeth position defining regions which guide the subject's teeth to grip the bite block in their natural position, with the teeth of the upper jaw positioned further out than the lower jaw teeth. These teeth position defining regions are also preferably curved to match the curved shape of the jaw. The upper and lower parts of the front plate of the bite block may also be positioned at different distances out, so that upper and lower lip regions both contact the front plate snuggly. The bite block may be used with separate oral/nasal cannulae, or may incorporate breath sampling or gas supply cannulae. A flexible flapped curtain at the outer end of the bite block may be provided to largely enclose the inner volume of the bite block to enable more accurate capnographic sampling under conditions of wide-open mouth breathing.

    摘要: A broadband digital communication network transmits a signal with a shaped power spectrum to minimize interference with devices that share the communication medium. In one embodiment using coaxial wiring, devices such as cable converters and televisions that are not part of the network share the communication medium and are exposed to the network signal. Power levels across the network band are selected to reduce interference in the non-networked devices. One area of susceptibility is the tuner of cable channel receivers, which perform mixing and down conversion of RF signals. The power spectrum profile is selected to minimize the IF and base band interference after down conversion. The spectrum can be shaped within each 6 MHz band to further minimize the interference with a TV signal. The power levels can be optimized for both peak power limitation and quantization effects.

    摘要: A broadband cable network (“BCN”) for determining a common bit-loading modulation scheme for communicating between a plurality of nodes in the BCN is disclosed. The BCN may include a transmitting node within the plurality of nodes where the transmitting node is capable of sending a probe signal to the plurality of nodes, and at least one receiving node within the plurality of nodes in signal communication with the transmitting node. The at least one receiving node is capable of transmitting a first response signal in response to receiving the probe signal. The first response signal includes a first bit-loading modulation scheme determined by the at least one receiving node. The transmitting node is further capable of determining the common bit-loading modulation scheme from the first response signal.

    摘要: Range extension within single user, multiple user, multiple access, and/or MIMO wireless communications. A given communication device designed and implemented for operation in accordance with a given communication protocol, standard, and/or recommended practice operates in accordance with a down-clocked manner to effectuate operation in accordance with at least one other communication protocol, standard, and/or recommended practice. For example, first channelization may undergo down-clocking by a particular and desired ratio to generate a second channelization. As such, at least one portion of a physical layer (PHY) of a given communication device may be leveraged for use in at least one other or additional operational mode based upon the down-clocking employed. Sub-channel and/or channel adaptation may be made based upon any of a number of considerations (e.g., independently by one device, cooperatively by two or more devices, local and/or remote operating condition(s) [or changes thereof], etc.).

    摘要: A base station (BTS) may instruct a client station (CS) to transmit sounding signals that the BTS may analyze to determine what adjustments, such as power, time, and/or frequency adjustment(s) should be made by the CS. The BTS may control when and how the sounding signals are sent by the CS. This helps reduce the possibility of adjustment signals transmitted by two or more CSs colliding. Thus, sounding signals transmitted by the CS in response to a request by the BTS can be received by the BTS with higher a probability of success. This permits the BTS to more accurately characterize the channel and to provide better adjustment of power level, frequency offset, and/or timing offset for more optimal communication. Such techniques can be used to reduce bit error rates and to improve the overall signal to noise ratio encountered by the system.
