It involves a discrete Fourier transform (DFT) pre-coding of the transmitted signal, where the DFT can be any one of 35 transform sizes N from 12-points to 1296-points, where N=2 a 3 b 5 c and a ...
In the Arria FPGA an ALM is two 4-input adaptive LUTs, four registers plus other logic. For the Arria 10 FPGAs, the goal of the design approach was to minimize the usage of FPGA LUT/register fabric, ...
