摘要： A radio communication system (100) provides a radio air interface at a master node (102) for subscriber units associated with the master node. Among the subscriber units are several slave nodes (104, 106). The communication system has the ability to operate as a secondary user in unused spectrum portions of a frequency band otherwise reserved for primary operators. The master node accesses an authorization server (108) to obtain a list of unused channels in the region of the master node. Each slave node also contacts the authorization server to obtain a list of unused channels in the region where each respective slave node is located, via another network (118, 121). The unused channels common to the slave nodes and the master node are used to create a backup radio operating parameter list which is used by the master node if a fault occurs between the master node the authorization server.

摘要： A method of retaining channel use by a secondary system is described. A secondary channel used during periods of normal communication between a secondary transmitter and receiver is split into sub-bands for use during a quiet period containing quiet phases. During the quiet period, while the transmitter communicates with the receiver on one sub-band, the receiver simultaneously senses for incumbent devices on another sub-band, as well as vice-versa. Transmission and sensing do not occur simultaneously on the same sub-band and transmission is limited to only one of the sub-bands. Transmission and sensing are performed by both the transmitter and the receiver on every sub-band over the course of the quiet period. The locations of secondary receivers are determined and employed during scheduling such that devices sufficiently separated from each other transmit during different quiet phases and transmit and sense in sub-bands separated by another sub-band.
摘要翻译：描述了通过辅助系统保持信道使用的方法。在次级发射机和接收机之间的正常通信期间使用的辅助信道被分成子带，以在包含安静阶段的安静时段期间使用。在静音期间，当发射机与一个子频带上的接收机进行通信时，接收机同时检测另一个子频带上的现有设备，反之亦然。传输和感测不会在同一子带上同时发生，传输仅限于一个子带。在安静时段的过程中，发射机和接收机都在每个子频带上执行传输和传感。在调度期间确定并采用辅助接收机的位置，使得彼此充分分离的设备在不同的安静阶段期间发送，并在由另一个子频带分离的子频带中进行发送和检测。

摘要： An apparatus and method of providing accurate and consistent open spectrum results for secondary devices from different geo-location databases is presented. The results, which may be independently derived by each database, are independent of the database queried. The comparison permits some amount of latitude in spatial and temporal consistency between the databases as errors are only indicated if the temporal or spatial discrepancies are pervasive. In addition, large percentages of different locations showing discrepancies when compared also lead to corrective action being taken. Corrective actions that may be taken include forcing problematic databases to update, shunting requests by secondary devices in the problematic locations to acceptable databases or shutting down the problematic databases entirely.

摘要： A programmable correlator for a communication system includes an input queue coupled with an analog-to-digital converter (ADC). The input queue includes a random access memory (RAM) wherein sampled data streams from the ADC are written into the RAM. The input queue has two banks of memory of width 2M. A flexible complex correlator is operable on M samples. The correlator is coupled to read M complex samples out of 2M samples from the input queue. A pseudo-noise (PN) crossbar unit operates to rotate a generated PN code to match a rotation of the input queue data in the complex correlator.

摘要： A cognitive radio (CR) system (102) includes CR units (108, 110) that determine and update location-based system operating parameters to avoid interference with other systems operating in the same frequency band. Operational Location Uncertainty region and Allowed Location Error regions can be applied. The CR unit trades off between both, available channels and maximum system operating parameters, such that as Location Uncertainty of the CR device increases, available CR channels and location-based CR system operating parameters decrease over a maximum network reach.
