Abstract: A wireless communication system having base stations, remotely located terminal units and a base station controller. The base stations and the remotely located terminal units communicate data over operational wireless communication links between them. The base stations include respective in-channel detectors and out-of-channel detectors for detecting radar or other extraneous received signals. The in-channel detectors analyse signals over the operational communication links. The out-of-channel detectors include respective out-of-channel receiver elements that monitor possibly available channels alternative to the respective operational communication link channels. The base station controller registers whether channels are available or not for communication links, and allocates to the base stations respective target channel parameters including frequencies available for operational and alternative communication links.

Abstract: A wireless communication system having base stations and remotely located terminal units. The base stations and the remotely located terminal units communicate data over operational wireless communication links assigned to respective sub-channels having tiles separated by frequency and time. Detectors for analyzing extraneous received signals in unassigned tiles of the communication links discriminate between a first type of extraneous signals detected in unassigned tiles of one sub-frame and also detected in other unassigned tiles, and a second type of extraneous signals detected in the unassigned tiles but not detected in other unassigned tiles. The reaction of the base stations is different based on the type of extraneous signals.

Abstract: A baseband signal modulator provides a phase and amplitude modulated carrier signal. First and second phase modulators each receive a common reference signal and derive therefrom a carrier signal frequency. The phase modulators each receive a respective pair of phase-encoded data signals so as to provide respective first and second phase-encoded carrier. The modulator outputs are summed to provide the phase and amplitude modulated carrier signal. Each phase modulator includes a respective phase locked loop incorporating an oscillator locked via the common reference signal to the carrier signal frequency, and a phase adder having a first input for receiving the carrier frequency signal and having second and third inputs for receiving the respective pair of data encoded signals.

Abstract: This invention relates to a radio transceiver operable in multiple modes. The transceiver is operable, in one embodiment, to communicate with digital and analogue modulation format cellular radio systems. The handset utilizes a novel frequency plan and architecture to enable a minimum level of complexity for dual-moe operation. The frequency plan preferably uses two local oscillators 1LO, 2LO to general all the required frequencies for both the digital and analogue modulation format transceivers, derived from a single reference crystal oscillator. A radio architecture is used to enable switchable dual-mode operation with maximum commonality of functional blocks to facilitate silicon integration.
