It is proved that a stochastic process (i.e., a Hilbert space valued function) indexed by a locally compact group is      V V      -bounded (i.e., weakly harmonizable in an appropriate sense) if, and only if, it can be expressed as an orthogonal projection of a process whose covariance function      R R       satisfies      R ( s , t ) = ρ  ( t −  1 s ) + ρ  ( s t −  1 ) R(s,t) = \rho ({t^{ - 1}}s) + \rho (s{t^{ - 1}})       for some continuous positive-definite function      ρ  \rho      . The result generalizes a well-known theorem due to H. Niemi, and depends on the noncommutative Grothendieck type inequality of G. Pisier.
