    DFT Based MMSE Equaliser in MIMO-OFDM

    MIMO-OFDM is considered as a fast growing technology now days. OFDM is a multi carrier modulation technique in which the carriers are Orthogonal to each others as a result of which it provides high bandwidth efficiency and multiple carriers share the data among themselves. During the research equalizer is always...

    Low Power H.264 Video Compression Achitecture for Mobile Communication

    This paper presents a method to reduce the computation and memory access for variable block size Motion Estimation (ME) using pixel truncation. Previous work has focused on implementing pixel truncation using a fixed-block size(16?16 pixels) ME. However, pixel truncation fails to give satisfactory results for smaller block partitions. In this...
