Frequency offset estimation in OFDM signals using particle filtering along with resampling methods
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Frequency offset is one of the main effects the Bit Error Rate(BER) in orthogonal frequency division multiplexing (OFDM). There are many applications which depend on OFDM. The present method describes the estimation of ...
Design issues in direct conversion receiver
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
The wireless system is being rapidly proliferated in our life. The growing of capacity in wireless communication requires a new type of wireless communication method which does not affect current work on circuits and systems ...
Orthogonal frequency division multiplexing synchronization techniques
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Synchronization plays a major role in the design of a digital communication system. Essentially, this function aims at retrieving some reference parameters from the received signal that are necessary for reliable data ...
Low noise amplifier design at 2 GHz
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Low Noise Amplifier (LNA) is one of the most important building blocks of any wireless
receiver. In this an attempt has been made to study two types of LNA designs. The first
design is the conventional which consists of ...
