Abstract:

The aim of this letter is to share a novel concept termed pseudo-pilot, which offers a simple and efficient approach of nonpilot-assisted channel estimation. Our key idea is to transfer the uncertainty of several payload symbols into the uncertainty of symbol interleavers by employing a bank of interleavers at the transmitter. Those uncertainty-transferred symbols serve as pseudo-pilots for the receiver to perform channel estimation. The uncertainty of symbol interleavers is then removed in the procedure of decoding. Performance and scalability of the pseudo-pilot technique are evaluated through both theoretical analysis and computer simulations.
