In this paper, we propose the residual carrier frequency offset tracking and sampling clock offset tracking algorithm that can be used in IEEE 802.11a and HIPERLAN Type 2 systems. Above Wireless LAN systems has short and long preambles, the carrier frequency offset is estimated and compensated. In case that the frame length is long, however, residual carrier frequency offset induces the severe performance degradation due to a phase rotation. And the sampling frequency offset also degrades the… CONTINUE READING
