Abstract
A permutated channel structure based on a block structure in talk-around direct communication is provided. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permutating the dedicated subchannels by cyclic shifts, whereby diversity gain can be maintained and interference between adjacent channels can be minimized.
