Orthogonal Frequency Division Multiplexing has become a key element of todays wireless communication systems. However, its sensitivity to oscillator phase noise is responsible for common phase error (CPE) and inter-carrier interference (ICI) which greatly degrades the overall system performance. In this contribution, we address the problem of reducing the… (More)
Fig. 5. Performance under fading and phase noise with BT = 0.01 for a coded system using a rate 1/2 convolutional code with iterative decoding / channel-phase noise estimation. For comparison, the performance of a PCC coding scheme with CPE estimation is plotted, along with the performance of the system with the ICI canceller . The plot also shows the ideal curves of a system with perfect estimation and no phase noise with and without using coding as well as the case of a coded system without any ICI reduction scheme but with perfect CPE estimation.
