本文提出了一种8x并行全数字基带接收机，支持IEEE 802.15.3c和IEEE 802.11ad标准下的SC和OFDM模式。全数字基带接收器包含4合1同步（SYNC）， 512点基数23 IFFT/FFT，相位噪声消除（PNC），共享存储器（MEM）组和频域均衡器（FDE），具有针对非视距（NLOS）和视距（LOS）信道的优化的基于goly相关器窗口的噪声消除（OGC-WNC）信道估计（CE）。SC和OFDM模式之间的硬件共享为99%，共享内存减少了51%的内存使用。测试结果表明，该芯片可提供9.24 Gb/s的PHY数据速率，功耗为497 mW，满足IEEE 802.15.3c和802.11ad标准中OFDM模式的要求。此外，在OFDM模式下，所制芯片的PHY数据速率达到14gb /s，功耗为698 mW，超出了在60 GHz传输环境下提供更高PHY数据速率的标准要求。
In this paper, an 8X-parallelism all-digital baseband receiver is proposed to support SC and OFDM modes for both IEEE 802.15.3c and IEEE 802.11ad standards. The all-digital baseband receiver contains a 4-in-1 synchronization (SYNC), a 512-point radix-23 IFFT/FFT, a phase noise cancellation (PNC), a shared memory (MEM) bank and a frequency-domain equalizer (FDE) with an optimized golay-correlator window-based noise cancellation (OGC-WNC) channel estimation (CE) for non-line-of-sight (NLOS) and line-of-sight (LOS) channels. The hardware sharing is 99% between SC and OFDM modes and the shared memory reduces memory usage by 51%. The measurement results show that the fabricated chip can provide PHY data rate of 9.24 Gb/s with power consumption of 497 mW to meet the requirement of OFDM mode for IEEE 802.15.3c and 802.11ad standards. Besides, the PHY data rate of the fabricated chip reaches 14 Gb/s with power consumption of 698 mW for OFDM mode that is beyond the standard requirement to offer higher PHY data rate over 60 GHz transmission environment.
