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...
متن کاملInnovations-based MAP detection for time-varying frequency-selective channels
By using the innovations process, this paper provides a unification and extension of the existing maximum a posteriori (MAP) detectors (MAPDs). The practically important topics of linear modulations, time-varying frequency-selective channels, differential phase detection, and fractional sampling are accounted for. The MAPDs are derived under different conditions of optimality and a priori knowl...
متن کاملDetection of Stbc Signal in Frequency Selective Fading Channels
Transmit diversity through two-transmit and one-receive antennas (DISO) with Alamouti’s Space-Time block coding (STBC) assumes the channel be flat and static over the coding block. Lindskog and Paulraj have extended this scheme for a time dispersive channel by doing the space-time coding over a large data block such as one burst. This helps to achieve diversity gain on a time-dispersive channel...

متن کاملMISO Concepts for frequency-selective channels
In order to limit interference and increase system capacity in CDMA systems, transmitted power required to achieve a certain performance should be as low as possible. Usually, receivers are designed to overcome the problems caused by the frequency-selective wireless channel. However, if the channel impulse response (CIR) is a priori known at the transmitter, the signal we want to transmit can b...
