Performance Evaluation of MIMO OFDM System by using Adaptive MMSE Equalizer
In wireless communication system, MIMO-OFDM has been proposed as an efficient technique for providing high date rates, low power consuming and very efficient in 3G and 4G technologies. MultipleInput Multiple-Output (MIMO) & Orthogonal Frequency-Division Multiplexing (OFDM) systems have a assuring ability to increase the capacity and performance with acceptable Bit Error Rate (BER) proportionall...

The demand for high-speed mobile wireless communications is rapidly growing. OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. In our proposed method Adaptive modulation techniques is used for maximizing the data throughput of subcarriers allocated to a user. It measures...
متن کاملPerformance Enhancement of WiMAX System using Adaptive Equalizer
The telecommunication industry has been developing at a very fast rate, but data networking service revenue has continued to rise. This paper presents on performance enhancement of the WiMAX system (Worldwide Interoperability for Microwave Access) by using Adaptive Equalizer. WiMAX is an emerging global broadband wireless system based on IEEE 802.16 standards. It is a new wireless OFDM-based te...
متن کاملPerformance Enhancement of WiMAX System using Adaptive Equalizer
Mobile WiMAX is a wireless networking system which provides wireless broadband to fixed and mobile terminals. In this paper, firstly performance evaluation of WiMAX system with channel estimation is discussed. Performance evaluation with channel estimation is used because amplitude and phase shift causes error in wireless channel. Finally, Performance evaluation of WiMAX system using adaptive e...
متن کاملAdaptive BICM-OFDM Systems
Link Adaptation for Orthogonal Frequency Division Multiplex (OFDM) systems is an important topic to achieve higher spectral efficiencies or better error rate performance. However, channel coding has been neglected previously, only gaining some attention recently. In this paper, an overview over existing techniques and algorithms to adapt Bit Interleaved Coded Modulation (BICM) systems are given...
