Webimplemented on a fixed-point processor is needed. The block floating point algorithm is based on the block automatic gain control (AGC) concept. Block AGC only scales values at the input stage of the FFT. It only adjusts the input signal power. The block floating point algorithm takes it a step further by tracking the signal strength from stage
