摘要： A method and apparatus for operation of a node within a mobile ad hoc cognitive radio network is provided. The method includes sensing at least one assigned communications channel. Sensing at least one assigned communications channel includes measuring a value of at least one parameter corresponding to the communications channel. The method further includes comparing the measured value of the at least one parameter with a set of stored values of the at least one parameter to determine a change in the measured values. Finally a sleep mode of the node is activated for a time period, wherein the time period is determined using the change in the measured values.

摘要： A transmitting device (100) transmits a first packet, comprising a second encryption vector, that is encrypted using a first encryption vector. The transmitting device transmits a second packet that is encrypted using the second encryption vector if an acknowledgement message is received within a predetermined time after transmitting the first packet; otherwise, the first packet is re-transmitted. Upon receipt of the first packet, a receiving device (102) decrypts the first packet using the first encryption vector and transmits the acknowledgement message. Upon receipt of the second packet; the receiving device attempts to decrypt a portion of the second packet using the first and second encryption vectors. If the portion of the second packet was successfully decrypted using the first encryption vector, the receiving device re-transmits the acknowledgement message for the first packet; otherwise, it transmits an acknowledgement message for the second packet.

摘要： A method of reducing power consumption in a communication device includes a step of acquiring a signal on a common pilot channel of a radio communication system. A next step includes detecting predetermined bits in the signal on the common pilot channel indicating activity on paging channels of the radio communication system. When no paging channel activity is indicated in the second step, a last step includes powering down portions of the electrical circuitry of the communication device so as to reduce power consumption, and when paging channel activity is indicated in the second step, a next step includes powering up portions of the electrical circuitry of the communication device such that those paging channels indicating activity are monitored by the communication device.

摘要： Efficient frequency spectrum sharing between at least one incumbent communication system(s) (102, 104) and at least one cognitive radio (CR) system (106, 108) is provided. The CR unit includes OFDM detection (216) for detecting the presence of OFDM signals which indicate the presence of an incumbent communication system within the shared spectrum. The CR system (106) updates channel occupancy information in response to the detected OFDM signals so as not to interfere with the incumbent communication systems (102, 104).

摘要： In accordance with the preferred embodiment of the present invention a gain (A) is determined and utilized to cyclically converge upon a quotient (Q). More particularly, once A is determined, an estimate of QN is multiplied by Y to estimate {circumflex over (X)}N, where Q=X/Y. The value of {circumflex over (X)}N is then subtracted from X to determine an error (eN), which is multiplied by A. The value of AeN(n) is added to AeN(n−1) to produce an estimate of Q. Once convergence has occurred, the value for Q is output from the circuitry.
摘要翻译：根据本发明的优选实施例，增益（A）被确定并用于循环地收敛于商（Q）。更具体地，一旦确定了A，将QN的估计乘以Y来估计XN，其中Q = X / Y。然后从X中减去XN的值以确定乘以A的误差（eN）。将AeN（n）的值加到AeN（n-1）以产生Q的估计。一旦发生收敛，Q的值从电路输出。
