“…To copy otherwise, to republish, to post on servers or to redistribute to lists, requires prior specific permission and/or a fee. To overcome the above problem, this paper proposes a blockspreading modulation scheme [3] [4] characterized in that a repeated data-block composition is used so as to achieve intra-cell interference (IraCI) free operation, leading to a total data-rate amounting to almost as many as the chip rate. Block-spreading single-rate schemes have been proposed in literature [5] [6].…”

For mobile systems higher than 3G, multi-rate data service is becoming an important issue. This paper proposes a multi-rate blockspreading CDMA system as an efficient scheme which is capable of intra-cell-interference free operation and inter-cell-interference reduction by a factor of reciprocal of the spreading factor. With a use of an accurate pilot transmission scheme, it is shown that a high frequency utilization efficiency can be achieved for various mixed data rate services.
