Block Transmissions on Orthogonal Carriers

Yazici, Ayhan
Baykal, Buyurman
Orthogonal Frequency Division Multiplexing (OFDM) and Single Carrier Block Transmissions (SCBT) are located at the two opposite edges of block transmission concept. In this paper a system which lies between OFDM and SCBT is proposed. The new system, namely Block Transmissions on Orthogonal Carriers (BTOC), can be considered as a hybrid form of OFDM and SCBT. BTOC system is investigated under the redundant filterbank precoders and equalizers framework. Peak-to-average power ratio (PAPR) of BTOC is formulated. Effect (of frequency offset for BTOC is also investigated. Simulation results showing the BER vs. SNR performances of zero-pad OFDM (ZP-OFDM) and cyclic prefix OFDM (CP-OFDM) as types of OFDM, zero-pad only (ZP-Only) as a type of SCBT and BTOC are also included.
