Performance Analysis of Carrier Frequency Offset (CFO) and Phase Noise in 4G Communication System
Abstract: For telecommunication services the dramatic shift in the market has been made in beginning of 21st century. In these days' communication network the key challenges is to integrate numerous serves, convey the additional data as expeditiously as doable through limited bandwidth and providing high information data rates. For 4G communication systems 3GPP introduced two features Higher Order Modulation and Multiple Input Multiple Output (MIMO) in OFDM system but one limiting …

BER Analysis of STBC MIMO-OFDM with ICI Cancellation
Abstract: AbstractSpace Time Block Code (STBC) Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) has been considered as the best technology for upcoming wireless communication systems because of its capability to transmit large data rates. But the given systems suffer from various major problems; like Carrier Frequency Offset (CFO), timing offset carrier phase noise and Intersymbol Interference (ISI) issues. In this research work, the carrier frequency offset has been …

Estimation of Semi-Blind Channel for Two-Way Relay by Using CRB: Pilot-based and Random Pilot-based
Abstract: The main purpose of semi-blind channel estimation scheme is for frequency-selective channel estimation, for multi-input and multi-output (MIMO) on relay networks, for using high bandwidth efficient use of spectrum. This scheme motivate to the low complexity of system to allow exchange information users to users by using an intermediate relay node. Because of superposition of signals at the relay node, section receiving signal at the user terminals is affected by …
