Abstract
This paper presents an analytical study on the new spreading matrix for Block Spread OFDM known as the Rotation Spreading Matrix and simulates the BER performance in the MMSE equation. In [1] a new spreading matrix was presented for Block Spread OFDM (BSOFDM) known as the Rotation Spreading Matrix. It was shown to greatly improve on the existing spreading matrices such as the Hadamard and the Rotated Hadamard matrices in frequency selective channels such as the ultra wide band and slow fading channels. This paper studies the effect of increasing the block size in BSOFDM using this new matrix.
