Channelized active noise elimination (CANE) for suppressing quantization noise in bitstream modulated transmitter (BMT)

Abstract Bitstream modulated transmitters may offer improved power efficiency and linearity simultaneously in RF power amplifiers. Several modulation techniques including envelop delta-sigma modulation and envelope pulse width modulation have been applied. The out-of-band quantization noise associat...
