摘要： An adaptive communication device includes a transceiver that communicates with a first remote communication device in a millimeter wave frequency band in accordance with a first protocol. The transceiver generates conflict detection signals based on signals received from a second remote communication device that communicates in accordance with a second protocol. A conflict detection module detects communication by the second communication device based on the conflict detection signals and generates a model trigger signal in response thereto. A conflict modeling module responds to the model trigger signal by generating idle prediction data based on the conflict detection signals, wherein the idle prediction data predicts an idle period in the communications by the second remote communication device. A transmission control module generates transmit control signals based on the idle prediction data, wherein the transceiver times transmissions sent to the first remote communication device based on the transmit control signals.

摘要： Aspects of a method and system for a transmitting antenna selection failure recover mode are presented. Aspects of the system may include a transmitting mobile terminal that enables selection of a sequence of protocol data units (PDU), for example a sequence of sounding frames, which may be transmitted during an antenna selection procedure. During transmission of the selected PDU sequence, the transmitting mobile terminal may receive an antenna selection failure indication frame. The transmitting mobile terminal may enable retransmission of at least one previously transmitted PDU in the PDU sequence based on the failure indication. Transmission of subsequent PDUs in the PDU sequence may resume after the retransmission. Alternatively, upon receipt of the failure indication frame the transmitting mobile terminal may restart the selected frame sequence from the beginning, or may select a subsequent PDU frame sequence.

摘要： A circuit is provided to carry out conversion and an analog signal into a digital signal, simultaneously with compression of the analog signal. An input analog signal buffered by a sample-and-hold circuit is supplied to a chain of amplifier stages having equal gains greater than 1. A set of comparators compares the output signal of each amplifier stage with a reference value. As soon as the output of any amplifier stage exceeds the reference value, an output of the corresponding comparator becomes active indicating the number of amplifier stages that were required to make the input signal higher than the reference value. A digital output device uses the comparator output signals to produce a digital signal proportional to the input signal level. As the amplifier chain is arranged so as to increase its total gain for a lower level of the input analog signal with respect to its total gain for a higher level of the input analog signal, the conversion circuit compresses the input analog signal simultaneously with its conversion into the digital signal.
