This paper lays the foundation for a quantitative theory of Gabor expansions f (x)= k, n c k, n e 2?in:x g(x&k;). In analogy to wavelet expansions of Besov Triebel Lizorkin spaces, we show that the correct class of spaces which can be characterized by the magnitude of the coefficients c k, n is the
