AbstractIn this paper, a new 8-channel integer-valued lapped transform, called the Integer Lapped Orthogonal Transform (ILOT), is proposed. The new transform can be implemented using simple integer arithmetic and has very low implementation complexity. Using 5-bits to represent its transform kernel, it was found that good coding gain and stop band attenuation, similar to the LOT, could be achieved. The multiplier-less fast ILOT requires only 106 additions and 42 shifts and can be implemented in 32-bit integer arithmetic [13].
