Analysis of Preamble and Synchronization Errors Estimation in Wireless OFDM Communications
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
Global mobile data usage increase by almost threefold [4] in the year 2010 . This increased data usage is from the rise in the number of consumer electronic devices that rely on wireless standards such as IEEE802.11 (Wi-Fi), IEEE802.16 (WiMAX), and cell phones in particular multi-function smart phones . The rising number of devices that require high data rates is placing increasing demands on bandwidth. One of the ways these challenges are being met is with the use of orthogonal frequency division multiplexing (OFDM). OFDM is not only spectrally efficient but resilient to the effects of the multipath wireless channel. Another technique being used is multiple input multiple outputs (MIMO). MIMO has already been incorporated into the IEEE802.11n, IEEE802.16e, and 4G cellular wireless standards. The introductions of MIMO into these standards make possible the increased data throughput and range required by many devices without increases in transmit power or bandwidth.
