Dynamic digital up and down converters

A method of dynamically operating a communication system, the method comprising:

• receiving a page header from a call processing software module that indicates the desire to frequency hop;
• determining if the requested frequency hop is permitted;
• when the frequency hop is permitted,
• retrieving parameters associated with the frequency hop;
• implementing the parameters in a digital up converter;
• and
• processing a page of data associated with the page header through the digital up converter.

A communication system, the communication system comprising:

• a transmit engine adapted to transmit complex data samples;
• a timing circuit adapted to control the timing of the complex data samples transmitted through the transmit engine;
• and
• at least one digital up converter, each digital up converter adapted to dynamically change at least one of filter coefficients, NCO frequency, interpolation/decimation rates and sampling rates based at least in part in information contained in a page header, the digital up converter further adapted to convert the complex data samples to passband signals.

A radio head interface card comprising:

• one or more digital up converters, each digital up converter adapted to convert complex digital data samples to passband signals of a select protocol based upon at least one of filter coefficients, NCO frequency, interpolation/decimation rates and sampling rates loaded in the digital up converter;
• one or more digital down converters, each digital down converter adapted to convert the passband signals to the complex digital data samples of a select protocol based upon the at least one of filter coefficients, NCO frequency, interpolation/decimation rates and sampling rates loaded in the digital down converter;
• and
• a controller adapted to read protocol information in a page header associated with the complex data samples, the controller further adapted to load filter coefficients, NCO frequency, interpolation/decimation rates and sampling rates in associated up and down converters based at least in part on the protocol information in the page header.

A server in a communication system comprising:

• one or more radio head interface cards, each radio head interface card adapted to communicate with a radio head unit, each radio head interface card including,
• one or more digital up converters, each digital up converter adapted to convert complex digital data samples to passband signals of a select protocol based upon parameters loaded in the digital up converter;
• one or more digital down converters, each digital down converter adapted to convert the passband signals to the complex data samples of a select protocol based upon parameters loaded in the digital down converter;
• a controller adapted to read protocol information in a page header associated with the complex data samples, the controller further adapted to load the parameters in associated up and down converters based at least in part on the protocol information in the page header;
• and
• an interface adapted to pass information traveling between the radio head interface card and a call processing module.
