Full-Rate, Full-Diversity, Finite Feedback Space-Time Schemes with Minimum Feedback and Transmission Duration
Lakshmi Prasad Natarajan, B. Sundar Rajan
In this paper a MIMO quasi static block fading channel with finite N-ary delay-free, noise-free feedback is considered. The transmitter uses a set of N Space-Time Block Codes (STBC…
An Adaptive Conditional Zero-Forcing Decoder with Full-diversity, Least Complexity and Essentially-ML Performance for STBCs
Lakshmi Prasad Natarajan, B. Sundar Rajan
A low complexity, essentially-ML decoding technique for the Golden code and the 3 antenna Perfect code was introduced by Sirianunpiboon, Howard and Calderbank. Though no theoretica…
Generalized Distributive Law for ML Decoding of Space-Time Block Codes
Lakshmi Prasad Natarajan, B. Sundar Rajan
The problem of designing good Space-Time Block Codes (STBCs) with low maximum-likelihood (ML) decoding complexity has gathered much attention in the literature. All the known low M…
On the Sphere Decoding Complexity of STBCs for Asymmetric MIMO Systems
Lakshmi Prasad Natarajan, K. Pavan Srinath, B. Sundar Rajan
In the landmark paper by Hassibi and Hochwald, it is claimed without proof that the upper triangular matrix R encountered during the sphere decoding of any linear dispersion code i…
Distributed STBCs with Full-diversity Partial Interference Cancellation Decoding
Lakshmi Prasad Natarajan, B. Sundar Rajan
Recently, Guo and Xia introduced low complexity decoders called Partial Interference Cancellation (PIC) and PIC with Successive Interference Cancellation (PIC-SIC), which include t…
A New Full-diversity Criterion and Low-complexity STBCs with Partial Interference Cancellation Decoding
Lakshmi Prasad Natarajan, B. Sundar Rajan
Recently, Guo and Xia gave sufficient conditions for an STBC to achieve full diversity when a PIC (Partial Interference Cancellation) or a PIC-SIC (PIC with Successive Interference…
Asymptotically-Optimal, Fast-Decodable, Full-Diversity STBCs
Lakshmi Prasad Natarajan, B. Sundar Rajan
For a family/sequence of STBCs , with increasing number of transmit antennas , with rates complex symbols per channel use (cspcu), the…
