چکیده
ABSTRACT In this paper, we show the equivalence of Space-Time block coding to multipath propagation with respect to Cyclic Delay Diversity for OFDM systems. Hence, we can apply existing Space-Time code design criteria and analyze methods for Space-Time code construction using Cyclic Delay Diversity OFDM systems in multipath propagation environments. i.e. terms like "diversity gain" and "coding gain" can be used to design, analyze, compare and understand these OFDM systems from the Space-Time block coding point of view.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier block modulation scheme suitable for wireless communications. It is primarily used in high bit rate systems to mitigate inter-symbol interference (ISI) caused due to delay spread. While the ISI caused by delay spread is an annoyance factor, it also provides multipath diversity advantage if the path gains fade independently. Fo...

In this paper we investigate the suitability and performance of space-frequency block coded Multi-band orthogonal frequency division multiplexing (MB-OFDM) system under UWB channel model. The employment of transmit diversity techniques based on block codes is expected to achieve enhancement in such systems since it greatly reduces the detrimental effects of multipath fading.

In this paper, we propose a multiuser detection (MUD) scheme for space-time block coded orthogonal frequency division multiplexing (STBC-OFDM) systems. We derive the optimum weight matrix used to decouple simultaneously signals from active multiple access users using the minimum mean square error (MMSE) multiuser detection method.

In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...
