Abstract

- The total transmission bandwidth and component carrier aggregation proposed by LTE-Advanced, sets a new challenge to the design of terminals. This article presents a way to assure terminals cope with the large bandwidth in an efficient manner. Various filtering methods are explored showing that an SDR architecture, such as ADRES (Architecture for Dynamically Reconfigurable Embedded Systems), is suitable for dynamic adaptation of filtering methods as function of the aggregation scheme and the individual bandwidth assigned to each terminal. This method is able to reduce the processing load by 70% for LTE-A with legacy support and possibly higher reduction when LTE legacy is not supported. Simulations conclude that the performance loss derived from the proposed method is marginal with no negative repercussion on the posterior baseband stages.
