Abstract
A space

is constructed and some characterizations of space

are given. It is shown that the classical Fourier transform is extended to the distribution space

, which can be embedded into the Schwartz distribution space

continuously. It is also shown that

is the biggest embedded subspace of

on which the extended Fourier transform,
