Channel Estimation for Wireless OFDM Communication Systems
Orthogonal Frequency Division Multiplexing (OFDM) has become a very popular method for high data rate wireless communications because of its advantages over single carrier modulation schemes on multi-path, frequency selective fading channels. However, inter-carrier interference due to Doppler frequency shifts, and multipath fading severely degrades the performance of OFDM systems. Estimation of...
متن کاملMimo-ofdm Communication Systems: Channel Estimation and Wireless Location
In this new information age, high data rate and strong reliability features our wireless communication systems and is becoming the dominant factor for a successful deployment of commercial networks. MIMO-OFDM (multiple input multiple outputorthogonal frequency division multiplexing), a new wireless broadband technology, has gained great popularity for its capability of high rate transmission an...
متن کاملOFDM ( A ) for wireless communication
This report is a tutorial on Orthogonal Frequency Division Multiplex (OFDM) and Orthogonal Frequency Division Multiple Access (OFDMA). OFDMA is the major transmission and access technology for future mobile broadband systems like Mobile WiMAX and 3GPP Long Term Evolution (LTE). One of the key features of OFDM and OFDMA is the ability to handle multipath propagation without complex receivers. Th...
متن کاملOFDM: Back to the Wireless Future
A key limitation for wireless technologies has been slow transmission rates that didn't come close to providing the capabilities of wireline services. This left the technologies unable to offer fast downloads or handle mul-timedia and other desirable applications. Now, however, wireless approaches that use orthogonal frequency division multiplexing (OFDM)—a modulation technique for transmitting...
متن کاملChannel Estimation in Wireless OFDM Systems
Orthogonal frequency division multiplexing (OFDM) provides an effective and low complexity means of eliminating intersymbol interference for transmission over frequency selective fading channels. In this paper investigation and comparison of various efficient pilot based channel estimation schemes for OFDM systems has been done. The channel estimation can be performed by either inserting pilot ...
