A method and system for managing Digital to Time Conversion (DTC) is provided. The method comprises receiving a first Radio Frequency (RF) signal and a second RF signal. The second RF signal is a phase-shifted first RF signal. The method further comprises converting the first RF signal to a first Intermediate Frequency (IF) signal and the second RF signal to a second IF signal. Further, a time delay between the first IF signal and the second IF signal is estimated based on a time difference measurement technique. The second RF signal is processed based on the estimated time delay to compensate for a delay error associated with the second RF signal.

Method and system for managing digital to time conversion

A method, system and apparatus for managing communication in a Public Safety Communication Network (PSCN). The PSCN includes a plurality of Mobile Stations (MSs) () and a master controller (). The method includes initiating a communication between one or more MSs and the master controller using a primary channel (). 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 (). 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 (). The channel hopping pattern corresponds to a sequence of frequency hops for a MS.

A wireless communication network is provided in which a plurality of radio devices achieve frequency diversity. By utilizing cognitive capability within the radio devices to iteratively select frequency sets, a lowest cardinality frequency set is generated and used to communicate amongst the plurality of radio devices. Each radio device can have different hardware, as the iterative selection of frequency set can take into account the different hardware capabilities of the radio devices.
