In this paper, a phase noise cancellation (PNC) architecture is presented for 60 GHz communication systems. The BER performance is severely degraded by the non-ideal carrier frequency in 60 GHz bandwidth, which causes both common phase error (CPE) and residual carrier frequency offset (RCFO). The proposed simplified two-stage CPE algorithm solves the RCFO and common phase nose in the frequency domain and eliminates the constellation rotation on each sub-channel. Two-stage architecture together with deep pipelining technique achieves a high throughput rate. This PNC architecture has been implemented in a SC/OFDM Dual-Mode baseband receiver satisfying the requirements of the 802.15.3c/802.11ad standard with a 40 nm process. The proposed PNC is able to support 64QAM/16QAM for OFDM/SC mode, and can achieve up to 19.2 Giga-hit per second (Gbps) throughput rate at 400 MHz operating frequency with power consumption of 33 mW and area of 0.142 mm(2).

This work presents a dual mode, single carrier (SC) and high speed interface (HSI), wireless baseband receiver which implements the IEEE standards 802.15.3c 111 and 802.11.ad [2]. The proposed architecture of the baseband receive is designed as 8 parallelism with feed-forward data path reducing the operating frequency and can achieve high throughput for indoor communication. Besides, our goal is to demonstrate the system on Xilinx VC707 FPGA evaluation board and achieve multi-Gb/s data speed and low bit error rate (BER). The data rates achieved by the prototype are 1.5 Gb/s and 4.5 Gb/s for QPSK and 64QAM data in HSI mode, respectively. The specified (BER) of 10(-2) has been achieved for QPSK and 64QAM data at 8.3dB and 22.6dB, respectively.
