    摘要: A cooperative communications manager module establishes a first wireless link with a client device using a first channel frequency and dispatches a first message to the client device over the first channel frequency. The cooperative communications manager module establishes a second wireless link with a destination node and controls the cooperative transmission of the first message simultaneously with the client device to the destination node over the second wireless link using a second channel frequency. Other embodiments are described and claimed.

    摘要: Techniques are disclosed that involve communicating in bursty noise environments. For instance, a source device may send a probing packet to a destination device. This probing packet is for determining whether the communications medium (e.g., one or more frequency channels) is currently exhibiting a busy or jammed (e.g., due to bursty noise) condition. More particularly, based on whether an acknowledgment of the probing packet is received, the source device determines whether the channel is jammed (or busy) or clear. For example, an unacknowledged probing packet indicates that the channel is jammed or busy, while an acknowledged probing packet indicates that the channel is clear. If the channel is determined to be clear, then the source device may transmit one or more data packets to the destination device. Such data packet transmissions may be in accordance with a non rate-adaptive technique.

    摘要: An embodiment of the present invention provides an apparatus, comprising a receiver capable of selecting optimal pilot locations and providing feedback of the pilot locations to a transmitter in communication with the receiver. The optimal pilot locations may be selected by locations that avoid strong interference or platform noise at the receiver, by locations that avoid deep fading, by locations that maximize the spacing between pilot tones at the two ends of a wireless frequency band or by locations that equalize the interspacing between any two adjacent pilots.
