Spectrum efficiency and energy efficiency are two important attributes driving innovation in wireless communication. Efficient spectrum utilization and sharing with multiple access techniques and using under-utilized spectra by cognitive radios is the current focus due to the sc…
The new generations of CDMA communications systems (3G, 133G and 4G) and ad hoc networks are expected to support multirate services (multimedia applications, email, Internet, etc.) in addition to telephone service (fixed-rate service), which was the only service offered by 1G an…
