Subspace and pilot-aided methods for  channel estimation can be used to estimate the  nature of time varying channels. The simulated  performance of punctured and repetition codes  agrees well with the upper and lower theoretical  bounds in hard-decision decoding over Rayleigh and  Rician fading channels. The expression for the  upper bound on soft-decision decoding is also  derived and plotted. An adaptive forward error  correction (FEC) coding scheme is proposed to  combat the detrimental effects of fading in a  mobile multiuser environment. The throughput of the  proposed adaptive FEC scheme reaches the highest  code rate of the punctured convolutional code used.  The throughput of the proposed hybrid automatic  repeat request (H-ARQ) scheme exceeds that of the  generalized H-ARQ scheme for high signal to noise  ratios.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843374521\"\u003e\u003ch3\u003eAdaptive Rate Coding for A-CDMA Systems\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843374521","offer_id":39470069678173,"sku":"9783843374521","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/83afad6e-1842-4dd2-b357-b2beb54774c4.jpg?v=1770448717","url":"https:\/\/shop.autorenwelt.de\/products\/adaptive-rate-coding-for-a-cdma-systems-over-slowly-fading-channels-von-vidhyacharan-bhaskar","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
