    • A deployable antenna which has a larger aperture diameter by four-side links provided in at least three stages and which includes: six deployment link mechanisms (20) arranged radially from a central shaft so as to support an outer edge portion of a flexible reflector mirror surface; and one deployment driving mechanism (30) arranged at a lower portion of a center of arrangement of the six deployment link mechanisms, for unfolding the six deployment link mechanisms. Each of the six deployment link mechanisms includes a first four-side link (5), a second four-side link (6), and a third four-side link (7) arranged in an order from a position of the central shaft, around which the six deployment link mechanisms are arranged, toward an outer side of the each of the six deployment link mechanisms so that the each of the six deployment link mechanisms is structured to be foldable in three stages.

    • This invention provides techniques for a CDMA system having high spectrum efficiency with low transmit power. Each transmitter comprises means of selecting some core-sequences out of multiple sequences to make them convey plural data, means of producing an enveloped selected sequence with such a method as to arrange as guard sequences to a repeated sequence made by repeating each of the selected core-sequences, means of modulating a user specific orthogonal carrier frequency by the enveloped selected sequence to produce a transmit-symbol, and means of transmitting the transmit-symbols. And a receiver comprises means of demodulating a receive-symbol with one of the user specific carrier frequencies to produce a base-band receive-symbol, means of separating respective components corresponding to the sequences selected by the user, by analyzing the base-band receive-symbol with a matrix composed of a channel response vector from the user to the receiver to detect plural data on the components.
