A Review Paper on Analysis Of I/Q Imbalance and Impact of Timing Jitter and In OFDM Transmission Systems for ICI Reduction
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
in the past years tremendous progress has been made on the ofdm (orthogonal frequency division multiplexing) communication model and its applications, although all this progress, still impairments like timing jitter and i/q imbalance have huge impact on the system performance . As orthogonal frequency division multiplexing (ofdm) is the high data rate systems has the problem of inter carrier interference (ici) and due to timing jitter and i/q imbalance system leads the performance as high bit error rate. Analyzing the interaction between timing jitter and i/q imbalance a new algorithm is propose which leads the extra ici terms in their interaction. Indication of analysis is that the inter carrier interference (ici) has equal real and imaginary components and is independent of received subcarrier index .due to the relative contribution on timing jitter and i/q imbalance its parameters values influences the inter carrier interference (ici), whereas i/q imbalance dominating when timing jitter is relatively small and timing jitter taking over for larger jitter values. Observation shows the negligible interaction for extra ici in all cases. Analytical results will compare with simulation results for minimum ber.
