A Memory Access Reordering Polyphase Network for 60 GHz FBMC-OQAM Baseband Receiver

Abstract

In this paper, a novel memory access reordering polyphase network (PPN) for 60 GHz filter bank multi-carrier (FBMC) offset QAM (OQAM) baseband receiver is presented. The 8X-parallelism architecture of PPN is integrated into our 8X-parallelism digital baseband receiver. The PPN is designed based on IEEE 802.15.3c and IEEE 802.11ad standards. The PPN contains three key modules including memory bank, filter coefficient selector and 4-tap PPN filter. The proposed PPN is synthesized with 40 nm 1P9M general purposes (GP) process. The implementation result shows it can operate at specified 330/500 MHz clock rate with power consumption of 17/26 mW at 0.81 V supply voltage. With 8X-parallelism architecture, the sampling rate supports up to 2.64/4 GHz.
