Millimeter wave wireless communications are opening the way towards high data rate applications for WPAN scenarios. Multi-Gbps wireless systems are currently defined by standardization bodies. This paper presents a complete 60 GHz OFDM PHY layer proposal fulfilling the requirements of the IEEE 802.15 Task Group 3c. Data rates are ranging from 335 Mbps to 3 Gbps, with a high level of scalability. The proposed system is designed to operate in the 57 to 66 GHz frequency band, with a possibility to use channel sizes of 1 GHz and 2 GHz. The OFDM PHY layer allows scalable spectrum efficiency to achieve high data rates with flexible radio coverage. For a nominal channel bandwidth of 1 GHz, the system uses an FFT size of 1024, convolutional coding and advanced interleaving schemes. Simulation results show that this system is well suited for very high data rate applications in realistic scenarios.
