Abstract
A reconfigurable digital filter for a mobile terminal receiver has been analyzed in a simulated dynamic UTRA-TDD environment. By monitoring in-band and out-of-band power ratios, the filter architecture automatically scales its length to meet the signal to noise ratio of the system, This results in optimal battery power efficiency. Analysis reveals a 60 percent power saving for the receiver filter is available for the UTRA-TDD environment. This is compared to a static length filter that meets the 3GPP specifications. The savings in power will extend talk time and stand by time of the mobile terminal.
