Power Efficient Multi-Carrier Baseband Processing for 5G and 6G Wireless

“…Similarly, for the analog beamforming case, we need one PSS search per digital stream, obtaining the power, For the 28 GHz system we consider the mixer as passive devices. While for the 140 GHz fully-digital systems we use an active mixer design described in [18]. LO 80 63.57 76.…”

“…4. Evaluation of Design (1) and Design (2) in [18] using fixed-point 3GPP NR-like multi-carrier processing, 16 antenna elements at 140 GHz.…”

“…processing as described in Section III, and models for RFFE components at 140 GHz as described in [18]. Future releases will include models for RF components designed in other mmWave and THz frequencies and antenna element models.…”

“…A limitation of works such as [15]- [17] is that the components were not optimized for the overall end-to-end powerperformance trade-off. To overcome this issue, a recent work [18] developed a general methodology for performing this end-to-end power optimization given options for each component. The methodology was applied to a 140 GHz fullydigital receiver, with various device options were developed in each of the the critical RFFE components (e.g., LNA, Mixer, LO).…”

“…The broad scope of this paper is to extend the analysis in [17], [18] by providing initial power consumption estimates for the most important elements in the receiver baseband processing. We focus on a multi-carrier 3GPP New Radio (NR) like waveform [19].…”
