Low-density coding is one of the three techniques thus far developed for efficient communication over noisy channels with an arbitrarily low probability of error. A principal result of information theory is that if properly coded information is transmitted over a noisy channel at a rate below channel capacity, the probability of error can be made to approach zero exponentially with the code length. Any practical use of this theorem, however, requires a coding scheme in which the cost of storage and computation equipment grows slowly with code length. The present book analyzes a class of coding schemes for which costs grow approximately linearly with code length. It demonstrates that error probability approaches zero exponentially with a root of the block length and cites experimental evidence that this coding scheme has profitable aplicability in many communications situations.\u003c\/p\u003e","brand":"MIT Press","offers":[{"title":"Default Title","offer_id":42899601785087,"sku":"9780262571777","price":20.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0452\/0886\/2873\/products\/9780262571777-us-300_b40b94e7-1908-4aaa-97c3-7d35b3419858.jpg?v=1654560170","url":"https:\/\/massivebookshop.com\/products\/9780262571777","provider":"MASSIVE BOOKSHOP","version":"1.0","type":"link"}
