In accordance with the invention, a method includes determining either the number of tones per chunk required to compute per-chunk order responsive to a sub-band bandwidth, a coherence bandwidth and number of chunks, or the number of chunks responsive to a sub-band bandwidth and a coherence bandwidth; determining an order for each chunk; and determining, for each chunk, QR decompositions for all its tones according to the determined order.
