Abstract

This note provides derivation details of simplified OFDM transmission equation and resulting signal-to-interference plus noise ratio (SINR) for the case of an insufficient CP. Each channel component after demodulation is expressed as a single sum which can be interpreted a weighted Fourier transform of the channel impulse response.

Keywords

ofdm insufficient cp sinr simplified expression channel impulse response weighted fourier transform
