Abstract

In this paper, we proposed an all-digital self-interference cancellation (DSIC) with correction vector for convolution (CVC) technique to eliminate serious multipath self-interference for orthogonal frequency-division multiplexing (OFDM) full-duplex transmission in 60 GHz band. The CVC can solve the non-equivalence of circular and linear convolution. This work based on IEEE 802.15.3c/IEEE 802.11ad specification is synthesized with 40 nm 1P9M general purposes process. Under the Access Point (AP) and the User Equipment (UE) horn antennas being aligned face to face, the 9-bit fixed-point simulation result shows the proposed technique can achieve the target of the uncoded bit-error-rate (BER) of 10-2 at signal-to-noise ratio (SNR) of 24.8 dB satisfying the requirement of 26 dB.
