Frequency-hopped OFDM (FH-OFDM) technology will provide the additional benefits of frequency diversity and inter-cell interference averaging. However, it is difficult to get the channel state information. In this paper, we propose a method of channel estimation over slow fading channels for FH-OFDM systems. In the algorithm, the channel impulse response is estimated by correlation operation, by using...
Based on the m-sequence, a time-domain channel estimation algorithm for orthogonal frequency division multiplexing (OFDM) is designed. The m-sequence with cyclic prefix (CP) is inserted between OFDM symbols in time domain as training sequence. The cross-correlation is calculated between the received sequence with CP removed and the appointed circular shifted m-sequence, which takes reliability of...
