In this paper, we give a precise characterization of Parseval p-frames by the known Clarkson's inequality for ℓ p. As a direct application, we show that every tight p-frame {g j} j= 1∞ for ℓ p, with frame bound B> 0 and inf j‖ g j‖≥ C> 0, can be decomposed into⌊ B/C p⌋ standard q-Riesz basic sequences, and we show that the estimate⌊ B/C p⌋ is optimal. Moreover, we prove the existence of a p-frame which is not equivalent to any Parsevel p-frame for ℓ p, and a Parseval p-frame which is not a Schauder frame sequence for the space or its dual space, while we obtain that every p-frame can become a pseudo-framing with ℓ q coefficients for the dual space.
