Abstract: One embodiment is directed to a system for use with a coverage area in which one or more wireless units wirelessly transmit using a wireless radio frequency spectrum. The system comprises a first unit, and a plurality of second units communicatively coupled to the first unit using at least one communication medium. Each of the plurality of second units generates respective digital RF samples indicative of a respective analog wireless signal received at that second unit. Each of the plurality of second units communicates the respective digital RF samples generated by that second unit to the first unit using the at least one communication medium. The first unit digitally sums corresponding digital RF samples received from the plurality of second units to produce summed digital RF samples. The system is configured so that an input used for base station processing is derived from the resulting summed digital RF samples.

Abstract: A summing unit within telecommunications system includes: port to receive digital data stream from another device; and summer function. Digital data stream includes first and second digital data derived from first and second base station. First and second digital data comprises first and second digital values associated with respective time periods. Summing unit extracts first digital data from digital data stream. Summer function digitally sums first digital data with third digital data derived from third base station to generate summed digital data for conversion to radio frequency signals and transmission at antenna. Third digital data comprises third series of third digital values associated with respective time periods. Summer function digitally sums first digital data with third digital data by digitally summing (i) first digital value associated with respective time period and (ii) third digital value associated with respective time period to produce summed value for respective time period.

Abstract: Systems and method for resampling are provided. A method of resampling includes receiving a first sampled signal that is sampled at a first sample rate, where the first sample rate is a submultiple of a system clock rate for a Farrow filter. The method further includes resampling the first sampled signal, using the Farrow filter having a plurality of finite impulse response (FIR) filters and an arbitrary position interpolator, at a second sample rate to generate a second sampled signal. The interpolation factor for each sample of the second sampled signal is retrieved from at least one lookup table stored in memory and the first sample rate and the second sample rate are fixed and locked to a common frequency reference. The method further includes outputting the second sampled signal at the second sample rate.
