To meet the real time demand of HEVC intra encoding, this paper proposed a fast intra prediction algorithm and its design with a gradient weight controlled block size selection to reduce number of PU (prediction unit) sizes to two. These two PU sizes will be further selectively reduced to one based on its SATD distribution. The simulation results show that the proposed algorithm can save 79% encoding...
Although energy efficiency of communication systems has been studied for years, minimizing overall energy consumption of OFDMA downlink systems is still a challenge. In view of usual implementations, in this paper the energy consumption of control processor, specific circuit and analog front-end are jointly minimized, with algorithm complexity, resource scheduling, coding rate and modulation order...
