| Popis: | In this paper, we design an OFDM communication system with ICI cancellation embedded over LTE-R channel. In our proposed system, a very fast time-varying multipath fading channel is integrated with the use of D2a scenario of WINNER II channel model. The ICI cancellation approaches, wherein a PSK modulated symbol is mapped onto multiple subcarriers, are investigated and deployed in the Universal Software Radio Peripheral platform as the RF front-end. Experimental results confirm that the ICI cancellation techniques offer a notably high performance on eliminating the problem caused by frequency offsets. For instance, the ICI cancellation solutions achieve the same performance at Doppler frequency of 200 Hz compared to the system without using our approaches at a lower Doppler of 50 Hz. |
