Abstract
The invention concerns data processing by passage between different subband domains, of a first number L to a second number M of subband components. After determining a third number K, least common multiple between the first number L and the second number M: a) if K is different from L, it consists in arranging in blocs, by a serial/parallel conversion, an input vector X(z) to, obtain ppolyphase component vectors (p2=KL); b) applying a square matrix filtering T(z) of dimensions K×K, to the ppolyphase component vectors to obtain ppolyphase component vectors for forming an output vector Y(z), with p=K/M, and if the third number K is different from the second number M, providing a block arrangement by a parallel/serial conversion to obtain the output vector Y(z).
