Low-complexity co-channel interference cancellation and macroscopic diversity for high capacity PCS

Abstract

More than a factor of 3 increase in overall PCS capacity can be achieved in small, hand-held communication devices with limited battery power or in small, low-complexity base stations when incorporating simple interference cancellation techniques without training sequences in the channel access algorithm that realizes macroscopic selection diversity based on signal quality measurement. The comparison is done with respect to microscopic selection diversity and macroscopic selection diversity based on channel power measurement. Results were obtained by computer simulations.
