碩士 === 國立交通大學 === 電子工程學系 電子研究所 === 103 === In order to deal with the phase noise caused by the RF device which are required for 60GHz communication system might degrade the system performance. This thesis proposes a dual mode, low complexity and also achieves the specifications of the IEEE 802.15.3c standard phase noise cancellation (PNC) algorithm and hardware design. Meanwhile, its low complexity allows the implementation of baseband receiver. While in OFDM mode, a frequency domain algorithm for common phase error (CPE) cancellation and a feedback loop for long term residual carrier frequency offset tracking is provided in baseband receiver. As for SC mode, a two-stage phase noise cancellation algorithm is proposed and 99.8% of the hardware can be shared with the frequency domain algorithm for HSI mode. Besides, this thesis improves a single carrier (SC) mode and orthogonal frequency division multiplexing (OFDM) mode dual mode wireless receiver which is designed and implemented for IEEE 802.15.3c standard. There are five main functional blocks in the baseband receiver, which are boundary detection, sampling clock offset (SCO) cancellation, carrier frequency offset (CFO) cancellation, frequency domain equalizer, and phase noise cancellation. The hardware of key module between SC/OFDM modes are shared to reduce the hardware cost and power consumption. The baseband receiver works at 500MHz with 8X-parallelism architecture. The data rate can achieve 16 Gb/s and 24 Gb/s in SC mode and HSI mode, respectively. The area is 203 K gate count and the power is 297 mW. In NLOS channel, the un-coded BER at SNR 12dB can achieve 3.09×〖10〗^(-5) and 1.21×〖10〗^(-3)in SC mode and HSI mode, respectively.
