Abstract
Abstract In this paper, we verify the implementation of the Modified Cosine Roll‐off (MCR) spectrum for carrier pulse transmission systems that use the newly proposed MCR spectrum, and present various calculations. Specifically, we discuss the relationship between the filter placement and the interchannel interference, the relationship between the number of stages and the bandwidth of the receive filter that produces a zero crossing at the adjacent time slot, and the interchannel interference of channels having different speeds. The result shows that the MCR spectrum has the same degree of intersymbol interference as the cosine roll‐off spectrum and can decrease the channel spacing for cellular phones. © 2002 Wiley Periodicals, Inc.
