Summary on Grant Application Form |
|
The dramatic improvements in capacity (as much as 1000x the current level) and spectral efficiency that are needed for future wireless communication systems to accommodate the rapidly increasing number of wireless electronic gadgets and users who require access to ubiquitous high-speed wireless links can be achieved by adopting mm-wave (mmW) massive multiple-input multiple-output (MIMO) technologies. The realization of mmW massive MIMO requires a radical change in base station architecture wherein hundreds of power amplifiers are required to feed a large array of small antennas. The development of mmW massive MIMO transceivers has been hampered to date by the power amplifier's (PA) poor efficiency and high implementation cost. Nonlinear switch-mode power amplifiers (SMPAs) such as Class E and F offer high efficiency but require fast (power-hungry, expensive) transistors to allow the generation of higher order harmonics. Moreover, an abrupt drop during ON-to-OFF or OFF-to-ON transition in the idealised switch current or voltage waveform of existing SMPA topologies results in substantial power dissipation in the practical implementation, and hence reduces the PA efficiency. The proposed research ambitiously aims to produce a new type of highly-efficient, highly-linear power amplifier that offers true soft-switching characteristics to permit the use of low-cost, slow-switching transistors for effective deployment in mmW massive MIMO systems and thus open the way for very power-conservative high-performance systems.
