1. An apparatus for data processing for a wireless communications network, comprising:
a vector pipeline configured to scale, stage, and multiply twiddle factor to vector data from a mega-job;
a programmable mixed radix engine coupled to the vector pipeline and configured to be configurable for computing a plurality of jobs bundled in the mega-job in accordance with a DFT of a particular point size; and
a job scheduler coupled to the vector pipeline and operable to bundle multiple discrete Fourier transform (DFT) jobs having a substantially same point size into the mega-job after obtaining the DFT jobs.
