So, the MIMO give a solution to increase the data rate with out increment of transiting power or the channel bandwidth.Several method are conducting with the MIMO to increase the channel capacity such as; Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA) and Code Division Multiple Access (CDMA). In this work, the Orthogonal Space Time Block Code (O-STBC) MIMO Orthogonal Frequency Division Multiplexing (OFDM) system over flat fading channel is presented as the litterateur work.The QO-STFBC over OFDMA proposed to solve the incapability of O-STBC over selective frequency channel and to exployed the frequency diversity. The obtained results by using Matlab program showed the enhancement of the capacity.The QO-STFBC system examined over frequency selective channel,with 4 Tx and 4 Rx where are the SNR equal to 7dB and the obtained BER is 10-6.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659888144\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659888144","offer_id":39449998622813,"sku":"9783659888144","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/a75d59bb-0fec-45c9-aa87-f1038963f891.jpg?v=1769752361","url":"https:\/\/shop.autorenwelt.de\/products\/performance-of-multi-user-wireless-system-over-qo-stfbc-ofdma-von-duaa-al-budairy","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
