Detailed Description

The interleaver class.

The interleaver class performs interleaving as described in section 17.3.5.6 of the 802.11a-1999 standard. The Interleaver class contains two static functions: interleave and deinterleave and thus doesn't need a constructor. However, it does use the BitInterleave struct as a helper for these two functions.
