چکیده
|
Many wireless communication systems rely on orthogonal frequency division multiple access (ofdma) to guarantee reliable transmission and better performance. however,the orthogonality of the subcarriers has been destroyed by frequency offset (fo) and thus leads to inter-carrier interference (ici) which reduces the system performance. in order to overcome this problem,quarter ici self-cancellation (ici-sc) subcarrier mapping scheme using data allocation in space-time-frequency block codes (stfbc) for mimo-ofdma system is proposed. the technique is then evaluated through pairwise error probability (pep) and bit error rate (ber) performance. from the results,proposed quarter ici-sc subcarrier mapping scheme technique with stfbc shows the best result for mimo-ofdma system.
