Block differentially encoded OFDM with maximum multipath diversity
نویسندگان
چکیده
This letter proposes a novel block differentially encoded OFDM for multicarrier transmissions over frequency-selective fading channels. Choosing appropriate system parameters, we divide the set of correlated subchannels into subsets of independent subchannels. Within each subset, differential unitary space-time modulation is performed by treating each subchannel as a transmit-antenna. In addition to low complexity, the proposed system enjoys maximum multipath diversity, and high coding advantages. Analytic evaluation and corroborating simulations reveal its performance merits.

On the Equivalence of Space-Time Block Coding with Multipath Propagation and/or Cyclic Delay Diversity in OFDM
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 ...
متن کاملEXPLOITING TIME DIVERSITY IN SPATIALLY CORRELATED CHANNELS FOR OFDM SYSTEMS G.V.Rangaraj
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 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...

We present multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) based broadband power line communication (BPLC) using antenna and fading diversity. We evaluate the proposed MIMO-OFDM system over multi-conductor power line channels, with or without cross-talk between the antenna paths. The proposed scheme employs maximum ratio combining (MRC) that effectively com...
