Abstract
This paper presents a 3-finger rake receiver (RX) that exploits multipath characteristics in PN-modulated received signals to improve the signal-to-noise ratio (SNR) in full-duplex (FD) links. Orthogonality between PN codes allows up to 41.2 dB of TX self-interference (TX-SI) rejection and autocorrelation between delayed versions of received PN code improves the SNR by 9 dB. The receiver is implemented in 45-nm SOI CMOS and is tunable from 0.4 to 1.4 GHz with 30.5 dB of gain and an in-band/out-of-band baseband IIP3 of-6.5/14.2 dBm while consuming 45.8 mW per finger.
