Abstract:

The performance of the Orthogonal Frequency Division Multiplexing (OFDM) based systems degrades especially being sensitive to carrier frequency offset (CFO) and inphase and quadrature (I/Q) imbalance which destroys orthogonality between subcarriers. The IEEE 802.11ac (fifth generation) wireless local area network (WLAN) standard uses OFDM equally spaced subcarriers to transmit data, and the number of subcarriers signal depend on the bandwidth. In this paper, we investigate the system behaviour considering CFO and I/Q imbalance impairments. Our studies focus on two important non data aided algorithms. The results of analysis are presented for different subcarriers in combination with modulation and throughput.
