In frequency hopping spread spectrum (FHSS) systems, twomajor problems are timing synchronization and frequency estimation. A blind estimation scheme is presented for estimating frequency and transition time without using reference signals. The scheme is robust in the sense that it can avoid the unbalanced sampling block problem that occurs in existing(More)
When the duration of the cyclic prefix is shorter than that of the channel impulse response duration in single carrier-frequency division multiple access (SC-FDMA) systems, inter-symbol interference (ISI) and inter-carrier interference (ICI) will degrade the system performance. Previously, this problem was solved by a blind beamforming scheme with(More)
