WebMay 4, 2016 · $\begingroup$ You'll need to have good knowledge of the spacing if you want to effectively demodulate the signal. One area to start looking is to note that most OFDM implementations use a power of 2 FFT size (you noted 1024), and they also often use "nice" sample rates, like 20 MHz, 25 MHz, and so on. WebOct 15, 2012 · creating/destroying plans takes a lot of time relative to the FFT itself, so you're throwing away any speed advantage from using FFTW if you create/destroy a plan for evert FFT you perform; the frequency resolution will be different for each different size of FFT, which could make interpretation of successive output data troublesome.

OFDM demodulation, how to set the sampling rate?

WebDec 16, 2024 · FFT Size Determines how many individual frequency bands are analyzed. This option causes the most drastic changes in quality. The noise in each frequency band is treated separately, so with more bands, noise is removed with finer frequency detail. Good settings range from 4096 to 8192. WebThe execution time of fft depends on the length of the transform. Transform lengths that have only small prime factors result in significantly faster execution time than those that have large prime factors. In this example, the signal length L … husqvarna seat switch https://chriscrawfordrocks.com
