Abstract: A scalable VLSI architecture for Variable Block Size Motion Estimation (VBSME) in
H.264/AVC based on a full-search motion estimation algorithm is proposed in this paper. Through
rational design for the data flow and processing module array, the memory traffic is reduced;
data reusability in vertical direction is improved. Furthermore, the number of processing element
is configured according to the area-speed requirement, data reusability in horizontal direction is
controlled, and fast matching in large searching window is realized. After logic synthesis using
SMIC 0.13μm standard cell library, the search window size is 32×32, the number of gates is 338K
(3PEs) in two-input equivalent NAND gates and the maximum operating clock frequency is 300
MHz (1920×1088@70fps). Copyright © 2013 Binary Information Press.

Abstract: Laser is always affected by atmospheric turbulence in atmosphere transmission, and
channel estimation will become more difficult at poor atmospheric condition. According to Chadi
Abou-Rjeily's coding idea, introducing permutation matrix instead of negative form of symbols in
the real area Alamouti method, utilizing binary pulse position modulation, a differential
space-time code scheme that does not require channel estimates for free space optical
communication is proposed. The simulation results show that, compared with Alamouti coding
