Performance evaluation of Gbps OFDM PHY layers for 60-GHz wireless LAN applications

We present new Gbps orthogonal frequency division multiplexing (OFDM) physical layers and performance evaluations for applications of 60-GHz wireless local area network (WLAN). They are designed to operate in 57-66 GHz unlicensed frequency band with the possibility to use different channel bandwidth and to promise full compatibility to the channel plan that most 60-GHz standard groups have employed. Different modulation and coding schemes given by the designed OFDM physical layers allow scalable spectral efficiency to provide different payload data rates with different radio coverage. To facilitate practical hardware implementation with the designed OFDM physical layers, the performance evaluations are done with realistic 60-GHz channel models and 60-GHz nonideal RF front-ends models. The results confirm that the designed OFDM physical layer is suitable for high-data rate wireless LAN systems in practical application scenarios.
