Here, an adaptive coding scheme is also proposed by using Generalized Concatenated Codes (GCC), which have simple structure and are designed in such a way that they are best suited for fading channels. GCC are based on binary cyclic codes. The criterion of study is the optimization of throughput of the system. Through a proposed adaptive algorithm, a modulation selection scheme is proposed which is based on the quality of the Sub-channels. Moreover, a code assigning method for the different sub-channels, which adapts itself to the channel conditions is also proposed. The proposed scheme combats against channel impairments better than those used in conventional systems by exploiting individual sub-channel condition. Results show better performance in terms of lower bit error rate as well as higher throughput.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Romana Rafi,Rafi Us Shan\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3639260449\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783639260441\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/24\/2010\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 76\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.27lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.18d","brand":"Romana Rafi","offers":[{"title":"Paperback","offer_id":48454060605695,"sku":"9783639260441","price":52.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_d03cd0a9-2ea9-4e7f-bbd1-49d82c959c6f.jpg?v=1777303945","url":"https:\/\/www.whiterainbookhouse.com\/products\/adaptive-coding-and-modulation-romana-rafi-9783639260441","provider":"WR Book House","version":"1.0","type":"link"}
