Adaptive channel estimation and loading for OFDM based two-way relay systems
Joy, Arun (Dhirubhai Ambani Institute of Information and Communication Technology, 2013)In this thesis we introduce a low complexity Recursive Least Square (RLS) based Orthogonal Frequency Division Multiplexing (OFDM) channel estimation for two-way relay system. Using the estimate of the channel, a bit and ... -
Channel estimation and soft OSIC detection in coherent MIMO-OFDM systems using QRD techniques(802.16m)
Rawal, Divyang (Dhirubhai Ambani Institute of Information and Communication Technology, 2013)Next generation mobile systems will use multiple antennas at the transmitter and receiver to achieve higher capacity and diversity gain at high speeds. By transmitting through multiple transmitting and receiving antennas, ... -
Physical layer security: secrecy capacity analysis for multiuser networks using joint SVD-GSVD precoding technique
Tiwari, Tripti (Dhirubhai Ambani Institute of Information and Communication Technology, 2014)In this thesis, the problem of Physical Layer (PHY) Security is considered. This problem deals with secure signal transmission for a Multiple-Input Multiple-Output (MIMO) system using a relay i.e. the signal is transmitted ... -
Precoder design for beamforming in K-User MIMO interference chennel
Nivedita, S. (Dhirubhai Ambani Institute of Information and Communication Technology, 2014)Beamforming in MIMO wireless networks, is a techniques used for mitigating interference and achieve the best possible throughput. Accurate channel state information is essential for efficient design of beamforming vectors ...
