Abstract  Abstract

An excitation vector generator comprises a pulse vector generating section having N channels (N?1) for generating pulse vectors a storing section for storing M (M?1) kinds of dispersion patterns every channel in accordance with N channels a selecting section for selectively taking out a dispersion pattern from the storing section every channel a dispersion section for performing a superimposing calculation of the extracted dispersion pattern and the generated pulse vectors every channel so as to generate N dispersion vectors excitation vector generating section for generating an excitation vector from N dispersion vectors generated.
