WebI'm working on a modem system using a 16-QAM scheme. The transmitter runs an IFFT to modulate the signal, and has a 12-bit DAC. The receiver runs an FFT to demodulate the signal, and has a 12-bit ADC. Here are the general parameters: Sample rate is 512,000 SPS ; FFT size is 64 samples; 4 bits per bin/frequency with a total of 10 bins/frequencies.

The spectrum was generating by analysing a near perfect (mathematical) sawtooth audio clip, analysing it to extract out the harmonic mags and phases and then resynthesizing it via an IFFT using the extracted spectrum centering the start phase using the above line of code. The artifacts in the …
A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by … Meer weergeven The development of fast algorithms for DFT can be traced to Carl Friedrich Gauss's unpublished work in 1805 when he needed it to interpolate the orbit of asteroids Pallas and Juno from sample observations. … Meer weergeven In many applications, the input data for the DFT are purely real, in which case the outputs satisfy the symmetry $${\displaystyle X_{N-k}=X_{k}^{*}}$$ and efficient … Meer weergeven As defined in the multidimensional DFT article, the multidimensional DFT transforms … Meer weergeven An $${\textstyle O(N^{5/2}\log N)}$$ generalization to spherical harmonics on the sphere S with N nodes was described by … Meer weergeven Let $${\displaystyle x_{0}}$$, …, $${\displaystyle x_{N-1}}$$ be complex numbers.
