Operation Range Estimation of Reed-Solomon Coded SC-FDE System in 60-GHz WPANs

60-GHz band is a popular choice of industry for next generation wireless personal area networks, which will enable data rates in the order of Gbps. Single-carrier frequency domain equalization (SC-FDE) systems are proposed to obtain such high data rates in low-power and low-cost consumer products. In this paper, we are suggesting to use simple zero- forcing equalization to reduce the complexity requirement. We test system performance through simulations and find associated range of the WPAN. Our simulations take into account non-line- of-sight (NLOS) multipath channel model, channel estimation errors and RF impairments of phase noise and power amplifier distortion, to obtain realistic results. Our results show zero- forcing equalization can be employed in applications robust to delay such as file transfer between PCs and peripherals up to 4 meters. This result encourages the usage of 60-GHz band in low-power devices such as cellular phones and cameras. For applications which are sensitive to delay such as video streaming, more complex MMSE equalizer is required.
