Abstract

The implementation of transform precoding is one of the important steps for SC-FDMA baseband signal generation of physical uplink shared channel in TD-LTE. According to the definition of transform precoding, the mixed radix DFT which is made up of the radix-2, radix-3, radix-5 should be realized, and the transform length is not fixed. For unfixed DFT, this paper focuses algorithms, and designs an unfixed-point DFT universal module, which has already been achieved on the FPGA chip. Meanwhile, the hardware resources can be optimized, its processing speed and power consumption can basically meet the DFT requirements of uplink SC-FDMA in TD-LTE system.
