An w can transmit vry minimum numbr of cfigurati of. To incras th sp of communicati systm an incras th numbrs of cfigurati author sign som communicati systm by iffrnt ologis of Hamming co. About all ths communicati systms all ologis ar iscuss hr. First, author sign communicati systm to mak communicati by vn for 25 informati. In sc papr, author sign communicati systm to mak communicati by o for 25 informati. In thir papr, author again sign communicati systm for 25 informati by vn an o by using VHDL by singl systm. Till now, for 25 informati communicati is possibl ly in simplx mo. So that now author, sign 25 hamming co transcivr to mak communicati possibl in full uplx mo. Ky wor -- Hamming co, VHDL co, Xilinx ISE 10.1 simulator, vn, o, transmittr, rcivr, transcivr. 1. Hamming Co Mthoologis :- Hamming co is a linar rror-corrcting co nam aftr its invntor, Richar Hamming. Hamming cos can tct up to two simultanous rrors, an corrct singl- rrors; thus, rliabl communicati is possibl whn th Hamming istanc btwn th transmitt an rciv pattrns is lss than or qual to. By ctrast, th simpl co cannot corrct rrors, an can ly tct an o numbr of rrors.[5][6][15][16][19][21] In 1950 Hamming introuc th (7, 4) co. It ncos 4 s into 7 s by aing thr s. Hamming (7, 4) can tct an corrct singl rrors. With th aiti of ovrall, it can also tct (but not corrct) oubl rrors. Hamming co is an improvmnt. It can corrct 1 rror ly[5][6][15][16][19][21] Hamming co works ly two s (vn, o ) for gnrating runancy. In hamming co for gnrating th numbr of runancy us 9 formula.th numbr of runancy pns th numbr of informati s[1][2][3]. Formula for gnrating runancy ^ r >= D + r (1) Hr r = numbr of runancy D = numbr of informati Calculat th numbr of numbr of runancy for 25 of input by abov formula W gt 5 runancy rquir. 1.1 Runancy :- Th cntral ccpt in tcting or corrcting rrors is runancy. To b abl to tct or corrct rrors, w n to sn som xtra s with our. Ths runant s ar a by th snr an rmov by th rcivr. Thir prsnc allows th rcivr to tct or corrct corrupt s. Th ccpt of incluing xtra informati in th transmissi for rror tcti is a goo. But insta of rpating th ntir stram, a shortr group of s may b appn to th n of ach unit. This tchniqu is call runancy bcaus th xtra s ar runant to th informati.
