    摘要: A method, system and apparatus for managing communication in a Public Safety Communication Network (PSCN). The PSCN includes a plurality of Mobile Stations (MSs) (110, 115, 120) and a master controller (105). The method includes initiating a communication between one or more MSs and the master controller using a primary channel (405). The primary channel corresponds to a primary frequency spectrum in the PSCN. The method further includes identifying one or more available channels in one or more of the primary frequency spectrum and a secondary frequency spectrum (410). Each of the primary frequency spectrum and the secondary frequency spectrum include one or more channels. Thereafter, a channel hopping pattern is generated for one or more MSs based on one or more available channels (415). The channel hopping pattern corresponds to a sequence of frequency hops for a MS.

    摘要: Described is a method and an apparatus for performing the method to cancel interference caused by a windowing function applied to a signal prior to the signal being transmitted in a wireless communication system such as an OFDM system. The apparatus includes receiver apparatus that receives the signal to which the windowing function was applied. The apparatus further includes a processing device coupled to the receiver apparatus, and the processing device obtains (either by generating in substantially real time or retrieving from a storage device coupled to the processing device) a plurality of coefficients that are derived from the windowing function, and applies the coefficients to the received signal to cancel at least a portion of the interference from the received signal.

    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: A method for use in a digital communications receiver for controlling an input signal level (200) into an analog-to-digital converter (ADC) initially receives a sample sequence (201) where a threshold crossing rate is measured as a percentage samples of an input signal that exceed the threshold (203). The error between the measured threshold crossing rate and a desired reference threshold crossing rate is calculated (205) and an error signal is then utilized in a feedback loop to control the receiver gain such that the error is reduced (207).
