书籍  Bandwidth-Efficient+Digital+Modulation

Traditional modulation methods adopted by space agencies for transmit- ting telecommand and telemetry data have incorporated subcarriers as a sim- ple means of separating different data types as well ensuring no overlap between the radio frequency (RF) carrier and the modulated data’s frequency spe ...

书籍  Hybrid+Analog-Digital+Precoding

In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implementations. For this, we decompose the analog beamforming networks (ABFN) as a bank of commonly used RF compon ...

书籍  Interference+Mitigation+Techniques

This research work aims at eliminating the off-chip RF SAW filters from fre- quency division duplexed (FDD) receivers. In the first approach, a monolithic passive RF filter was constructed using on-chip capacitors and bondwire inductors. The bond- wire characteristics were studied in details and the ...
