Processing data presented in the form of a vector representation involves representing direction of the vector with incremental accuracy by using a set of vector codebooks of decreasing dimensions per accuracy increment.

1. A method, in a base station of decoding a channel signature of a frequency channel, the channel signature being encoded as a first codebook index and a second codebook index, the method comprising:
using the first codebook index and the second codebook index to determine a vector and a phase correction to the vector from a codebook; and combining the vector and the phase correction to determine a matrix indicative of the channel signature of a frequency channel.
