Keywords:
Interference Alignment, Space Time Frequency Block Codes, Carrier Frequency Offset, Intercarrier Interference, Bit Error Rate,Abstract
MIMO OFDMA system known as a good choice for high data rate wireless applications, but the factors such as carrier frequency offset (CFO) from frequency mismatching, time variations due to Doppler shift or phase noise has extensively destroys the orthogonality of the subcarriers which leads to inter-carrier interference (ICI) which severely degrades the performance of the system significantly. Hence, in this paper, the Space Time Frequency Block Codes (STFBC) technique and Interference Alignment (IA) scheme is applied to achieve the diversity and as an alternative approach to mitigate the ICI respectively. Through simulations, it is shown that the proposed scheme is able to improve the system performance in term of Bit Error Rate (BER).References
