Abstract:
The invention relates to a method of transmitting a signal comprising successive multi-carrier symbols with M subcarriers arranged in a frame, defined by a preamble comprising a first multi-carrier symbol: P 0 [ k ] = ∑ m = 0 M - 1 p m , 0 g [ k ] ⅇ j 2 π M m ( k - D 2 ) ⅇ j π m 2 and a second multi-carrier symbol: P 1 [ k ] = ∑ m = 0 M - 1 p m , 1 g [ mod ( k - N , M ) ] ⅇ j 2 π M m ( k - D 2 ) ⅇ j π ( m + 1 ) 2 . The pilot symbols pm,0 are such that: p m , 0 = { α m , m even 0 , m odd and p m , 1 = { p m , 0 ( - j ) , m even 0 , m odd with αm a real random variable.
