摘要

the object of the invention is the orthogonal frequency division multiplex method and device szinkronblokkjelelu0151u00e1llu00edtu00e1su00e1ra (u00e1tvitelirendszerhez ofdm), produced by the szinkronblokkjel, operating in the elju00e1ru00e1sszerint ofdm receiver, transmit data to a ofdm procedure system nt procedure ofdm synchronise receiver.the elju00e1ru00e1snu00e1lalkalmazott ofdm - szinkronblokkjel includes at least a first part (aszakasz), the ofdm signals generated by the segu00e9dvivu0151k su201326,26 modulu00e1lu00e1su00e1val alu00e1bbiakszerint: su201326,26 = n * {0, 0, 0, 0, 0, 0, 0, s1, s2, s3, 0, 0, 0, 0, 0, 0, 0, s4. 0, 0, 0, 0, s5, s6, 0, 0, 0, 0, 0, 0, s7. s8,0, 0, 0, 0, 0, 0, s9, s10,, 0, 0, 0, 0, 0, 0, s11, s12, 0, 0, 0, 0, 0}, where n is normalizu00e1lu00f3tu00e9nyezu0151,the first and at least a part of the idu0151tartomu00e1nybeli (section) ofdm precise ifft transzformu00e1lu00e1su00e1valu00e1llu00edtju00e1k signals 64.according to the invention, the at least one first section (section), a series of modulated segu00e9dvivu0151inek frekvenciatartomu00e1nybeli s1 = s1 are one of...s12:...s12 +, +, +, +, +, + of + of the, the, the, the, the...s12 s1 +, + =, + the + + + the, the, the, the, the, +, + +, however, the...s12 = s1 +, b +, however, (b (b,, the, the, the, (b, b +, +, and (b...s12 = s1 + (b +, b +, the,,, and (b) + (b, a, (b +, b +, however, the...s12 = s1 +, and (b), of the however, a + b, b +, b +, of, the,to (b +, b +,...s12 s1 = (b +, b +, in +, b +, +, +, + b, a + b, and (b), of these, or reverse order version, or a version of s1 to s12, where et was replaced by s11 s2 replace, etc. and where a = exp (j * 2 *? *????
