Cellular networks and technology have evolved substantially since the late 1970s, with
successive generations bringing a variety of new features. Each upcoming generation is …

Disclosed are a transmitter and method of combining multiple contiguous and non-
contiguous frequency bands in a wireless communication system using carrier aggregation …

A testbed is reported for the measurement of the instantaneous power dissipation of a dual
input Chireix power amplifier (PA) driven by an LTE signal. An FPGA system is used to …

Ultra-fast and energy-efficient connections are the keys to future wireless communication
technologies. However, even in full duplex communication systems, the accessible spectrum …

A novel wideband digital predistortion (DPD) technique that can relax the requirement for
sampling frequency is proposed. The proposed band-split parallel signal processing DPD …

This paper proposes a two-element LTE MIMO handset antenna with physically different
main and diversity antennas. The performance of the design is studied theoretically and …

For the efficient use of frequency spectrum under multi-band operation in 5th generation
mobile communication (5G), RF circuits that can flexibly switch multiple bands are important …

A highly efficient receiver architecture for intraband contiguous carrier aggregation (CA) is
described. The downconversion architecture is done in two stages; the first stage is done in …

Broadband power amplifiers are becoming increasingly important for communications and
radar phased array applications. Amplifying concurrent signals allows for increased data …

This paper proposes a non-linear distortion noise power control method which uses clipping
and in-band and out-of-band filtering methods for multi-band OFDM transmission. The …
