Power and frequency efficient virtual cellular network
Eisuke Kudoh, Fumiyuki Adachi · 2004
Recently, major services provided by mobile communications systems are shifting from voice conversations to data communications over the Internet. There is a strong demand for increasing the data transmission rate. However, an important problem arises; larger peak transmit power is required as transmission rate becomes higher. In this paper, a virtual cellular concept is proposed to avoid this power problem and its transmit power and frequency efficiencies are evaluated by computer simulation to compare with that of the present cellular systems.
