Space-Time block codes from orthogonal designs
TLDR
A generalization of orthogonal designs is shown to provide space-time block codes for both real and complex constellations for any number of transmit antennas and it is shown that many of the codes presented here are optimal in this sense. Expand
Space-Time Codes for High Data Rate Wireless Communications : Performance criterion and Code Construction
TLDR
Winding sections are assembled coaxially with one of the winding sections being of the encapsulated type and the other of the sealed type. Expand
Space-time block coding for wireless communications: performance results
TLDR
It is shown that using multiple transmit antennas and space-time block coding provides remarkable performance at the expense of almost no extra processing. Expand
A differential detection scheme for transmit diversity
TLDR
A transmission scheme for exploiting diversity given by two transmit antennas when neither the transmitter nor the receiver has access to channel state information and requires no channel state side information at the receiver is presented. Expand
Collaborative beamforming for distributed wireless ad hoc sensor networks
TLDR
The performance of collaborative beamforming is analyzed using the theory of random arrays and it is shown that with N sensor nodes uniformly distributed over a disk, the directivity can approach N, provided that the nodes are located sparsely enough. Expand
Optimized constellations for two-way wireless relaying with physical network coding
TLDR
The proposed modulation scheme can significantly improve end-to-end throughput for two-way relaying systems and is applicable to a relaying system using higher-level modulations of 16QAM in the MA stage. Expand
Combined Array Processing and Space-Time Coding
TLDR
This paper dramatically reduces encoding and decoding complexity by partitioning antennas at the transmitter into small groups, and using individual space-time codes, called the component codes, to transmit information from each group of antennas. Expand
Multiple-antenna channel hardening and its implications for rate feedback and scheduling
TLDR
A central limit theorem is proved for MIMO channels with a large number of antennas, which is described as a "channel-hardening" result for data and voice services, scheduling, and rate feedback. Expand
Achievable rates in cognitive radio channels
TLDR
An achievable region which combines Gel'fand-Pinkser coding with an achievable region construction for the interference channel is developed, which resembles dirty-paper coding, a technique used in the computation of the capacity of the Gaussian multiple-input multiple-output (MIMO) broadcast channel. Expand
Space-time codes for high data rate wireless communication: performance criteria in the presence of channel estimation errors, mobility, and multiple paths
TLDR
It is proved that in the absence of ideal channel state information the design criteria for space- time codes is still valid and the diversity order promised by space-time coding is achieved under a variety of mobility conditions and environmental effects. Expand
