Abstract

This paper describes the design and verification of IEEE802.22 WRAN physical layer. The WRAN physical layer is fundamentally based on the IEEE 802.16e system, but the OFDMA parameters including preamble structure and pilot pattern are newly designed by considering the WRAN channel environments. In this paper, we present the simulation models and results by using appropriate synchronization and channel estimation algorithms. From the results of those simulations, we can obtain 90% preamble detection probability at SNR more than -5 dB, and we can synchronize the CPE to the BS within 2 % of sub-carrier spacing at SNR more than about 1 dB. Moreover, by using the LMMSE algorithm to estimate the channel, we can reduce the performance degradation of 0.2~0.5 dB compared to ideal channel estimation. In conclusion, we have found that the proposed receiver meets the Functional Requirement Document (FRD) for WRAN physical layer.
