Channel estimation and soft OSIC detection in coherent MIMO-OFDM systems using QRD techniques(802.16m)
(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, ...
Adaptive channel estimation and loading for OFDM based two-way relay systems
(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 ...
Coordinated adaptive power management (CAPM) technique for sensor network nodes
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
Small size of wireless sensor nodes limit the size of the battery supported on it which directly limits the capacity of the battery and lifetime of the sensor nodes. Though energy scavenging is one of the solutions, it is ...
