Preamble design for symbol synchronisation in frequency‐selective fading channels

Low‐complexity method for primary synchronisation in the third generation partnership project long term evolution downlink system

“…These methods are also called initial cell search in the cellular system. There are two approaches for performing symbol synchronisation in an OFDM-based communication system: preamble-based [1][2][3][4][5][6][7][8][9][10] and CP-based [11,12]. In the preamble-based method, a training sequence is inserted within the signal at known specific places that could be used by the receiver to achieve synchronisation.…”
