Method and system for processing data flows

Method and system for processing data flows

The method and system supports multiple bandwidth traffic over a single CPRI (common public radio interface) link (109) using a single bandwidth DMA (direct memory access) engine (505) and fast Fourier transform/inverse fast Fourier transform processing. (402, 404) The invention exploits fast Fourie...

description The method and system supports multiple bandwidth traffic over a single CPRI (common public radio interface) link (109) using a single bandwidth DMA (direct memory access) engine (505) and fast Fourier transform/inverse fast Fourier transform processing. (402, 404) The invention exploits fast Fourier transform/inverse fast Fourier transform properties and is particularly suitable for supporting LTE (Long Term Evolution) cellular communication systems (100) The CPRI Media Access Control is configured in each CPRI lane to run at the maximum bandwidth among the bandwidths required.. In the uplink, lower bandwidth data samples are padded with zeros and flexible positioning may be used to arrange the data in a CPRI frame. In the downlink, the radio equipment receiver (106) only processes the relevant data and ignores any interpolated samples. The invention is compatible with CPRI and LTE standards.
