DSP implementation of OFDM communication system
no vote
Application background As one of the key technologies of OFDM, LTE is used more and more widely. This code is a OFDM communication system, which is a reference value in DSP. Key Technology OFDM (Frequency Division Multiplexing Orthogonal) is the orthogonal frequency division multiplexing (Modulation) technology. In fact, OFDM is a kind of MCM (Carrier) and multi carrier modulation. OFDM technology developed by MCM (Modulation Multi-Carrier, multi carrier modulation). OFDM technology is one of the ways to realize multi carrier transmission scheme and its modulation and demodulation is respectively based on IFFT and FFT to achieve, is to achieve the lowest complexity and the most widely used a multi carrier transmission scheme.
