Abstract
Joint channel and control information estimation in orthogonal frequency division multiplexing depends strongly on the properties of the pilot sequences used, particularly the maximum difference, autocorrelation and cross-correlation coefficients. Presented is a practical algorithm for generating near-optimal sequences which can achieve excellent performance even in the low SNR region.
