A study of GI-less in Parallel Transmission for OFDM system
This paper proposed a Guard Interval Less (GI-less) transmission on orthogonal frequency division multiplexing (OFDM) for Long Term Evolution (LTE). The system will utilise the application of parallel packet transmission and the useful operation of the characteristics of IFFT. In addition with perfect frequency equalizer FEQ, the intersymbol and interchannel interference can be eliminated. Therefore, the proposed system offered the similar performance of QOS at a reasonable complexity enhancement. In this paper, an in-depth overview of OFDM with focus on physical layer will be examined.
