摘要： A technique for a secondary communication system to utilize spectrum designated to another (or primary) communication system is provided. By ranking a plurality of secondary base stations based on base station transmit power, calculated required transmit power and path loss, a set of criteria is developed for selecting a highest ranked secondary base station for operation within a primary's spectrum. The ranking may be adapted based on mobility of the secondary's subscriber; and as such the secondary system communicates within the primary's spectrum using the adaptively ranked base stations. Channel selection may also be ranked. The technique and apparatus allows a cognitive radio (CR) network to operate within an incumbent network's spectrum.

摘要： A method (300, 400) and a communication system (104, 106, 200) for dynamic RF spectrum allocation among a plurality of RF transmitters (108, 110, 112). A message can be received from a first communication system. The message can include a request (130) for available RF spectrum over which to transmit RF signals. The message can indicate a geographic location of a first non-incumbent transmitter (112) associated with the first communication system. Further, for the RF spectrum, a maximum power level can be determined at which the first non-incumbent transmitter may transmit without exceeding a threshold level of interference at least one focal point (134). A RF spectrum list (138) identifying at least the RF spectrum and the determined maximum power level can be communicated to the first communication system.

摘要： A programmable correlator (114) for a communication system (100) includes an input queue (113) coupled with an analog-to-digital converter (ADC) (109, 110, 111). The input queue (113) includes a random access memory (RAM) wherein sampled data streams from the ADC (109, 110, 111) are written into the RAM. The input queue (113) has two banks of memory of width 2M. A flexible complex correlator (140) is operable on M samples. The correlator (140) is coupled to read M complex samples out of 2M samples from the input queue (113). A pseudo-noise (PN) crossbar unit (143) operates to rotate a generated PN code to match a rotation of the input queue data in the complex correlator (140).
