| Abstract(in English) | It is an important issue to compare band-width efficiency among various CDMA schemes in the literature. This paper intends to indicate the most promising scheme for the possible application in beyond 3G cellular communications. All candidate CDMA schemes are classified into four major groups, (A) matched filter RAKE reception which have been used in 2G-3G commercialized systems with interference canceller, (B) de-correlating reception with de-correlating detector (DD) or MMSE detector, (C) conventional block spreading modulation, in contrast to single spreading used in (A) and (B), and (D) efficient block spreading modulation. From the viewpoint of frequency utilization efficiency these schemes are compared in terms of data rate, data-block size, symbol rate and chip rate, under an equal gain channel with a fixed delay time 3μ sec.. It is concluded that efficient block spreading technique (D) is very promising for future high data rate systems to be constructed on much higher chip rate than that of 3G systems. |
