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":"Paperback","offer_id":47813612765335,"sku":"9780262571777","price":2878.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9780262571777.webp?v=1778337170","url":"https:\/\/atlanticbooks.com\/products\/low-density-parity-check-codes-9780262571777","provider":"Atlantic Books","version":"1.0","type":"link"}
