In [14, 15], the Walsh-Hadamard matrix and the discrete Fourier transform (DFT) operation have been used as precoding matrices to decrease the PAPR of the OFDM signals.
The final resolution (number of points) is bounded by the requirements of the Walsh-Hadamard Transform [27] used in the pattern analysis, which requires the number of data points (n) to be of the order of [2.sup.n].
The spatially uncorrelated feature of the transmission signals is produced using Walsh-Hadamard code sets; then multipath delayed waves are produced for each signal, and finally a different Doppler shift is added for each probe antenna.
For example, with [N.sub.T] = 4, the 4 matrices that are selected are the identity matrix [I.sub.N] corresponding to no transform, the Walsh-Hadamard transform (WHT) matrix [P.sup.W], the discrete cosine transform (DCT) matrix [P.sup.C], and the discrete Hartley transform (DHT) matrix [P.sup.H].
The Walsh-Hadamard transformation, operator to rotate phase and inversion about average transformation were achieved through matrices of zeros and ones available as Matlab commands.

The Walsh functions are row vectors of Walsh-Hadamard matrices.
The transformation that applies H to n bits is called the Walsh, or Walsh-Hadamard, transformation W.
(2) New codebooks for SSK are introduced and their performance is investigated, including the Full-Combination (FC), Walsh-Hadamard (WH), Quasi-Orthogonal Sequences (QOS), and Orthogonal Array Testing (OAT) codebooks.
An orthogonal code such as Walsh-Hadamard code is used to achieve minimum multiple access interference (MAI) in the fading channel.
