摘要: 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.
