- W1858530204 abstract "In this paper, the physical layer of a 3.6864 Mcps wideband CDMA system which has been proposed by ETRI for FPLMTS (future public land mobile telecommunication systems) is described. It is designed to be adequate upto a 5 MHz bandwidth in order to make it easy that frequencies are allocated to carriers by multiples of 5 MHz bands and make the specification of pulse shaping filter more loose. 8 kbps CS-ACELP (conjugate structure algebraic CELP) is adopted as a main vocoder algorithm and 32 kbps ADPCM can be used. In the reverse link, the continuous pilot scheme is introduced to cope with discontinuous data transmission and to have a symmetrical H/W component to the forward link. In order to maintain the service quality with heavy signaling data, signaling activity with a dedicated signaling channel is introduced for spectrum efficiency. The user information data of upto 128 kbps can be transmitted by using QPSK data/QPSK spreading, variable spreading factor, and code pair assignment. Based on the 3.6864 Mcps system, the multiband 0.9216/3.6864/14.7456 Mcps system for multilayered cell environments is under consideration for FPLMTS." @default.
