This paper characterizes the capacity of a class of modular additive noise relay channels, in which the relay observes a corrupted version of the noise and has a separate channel to the destination. The capacity is shown to be strictly below the cut-set bound in general and achievable using a quantize-and-forward strategy at the relay. This result confirms(More)
Conditional capture and conditional precharge techniques for high-performance flip-flops are reviewed in terms of power and delay. It is found that application of conditional techniques can improve Energy-Delay Product for up to 14% for 50% input activity and save more than 50% in power consumption for quiet input. This property makes conditional methods(More)
A unique color interpolation approach for digital still cameras is introduced and described in terms of color vectors. A new difference plane model is introduced and used in conjunction with the proposed here correction process. This avoids edge blurring while improving on the color appearance of previous methods. Experimental results indicate that the(More)
A dual-edge triggered flip-flop suitable for low power applications is presented. HSPICE simulations conducted in 0.11u CMOS technology using 1.2V power supply voltage show that the proposed design is comparable in energy-delay product to highperformance single-edge triggered flip-flops while maintaining lower clock power. The Energy-Delay Product(More)
This paper describes a coding scheme for approaching the maximum theoretical decode-and-forward rate for the relay channel in the high signal-to-noise ratio (SNR) regime. The proposed scheme is based on a concatenation of bit-interleaved coded modulation (BICM) and a specially designed bilayer low-density parity-check (BLDPC) code that works simultaneously(More)
A new dual edge-triggered flip-flop that saves power by inhibiting transitions of the nodes that are not used to change the state is presented. The proposed flip-flop is 12% faster with 10% lower Energy-Delay Product for 50% data activity, as compared to the previously published dual edge-triggered storage elements. This was confirmed by simulation using(More)
The paper introduces a new color filter array (CFA) interpolation method for digital still cameras. The proposed interpolation scheme is able to (i) overcome the hardware limitations of existing CFA based image acquisition solutions, and (ii) restore color images with excellent visual quality. The scheme employs an adaptive edge-sensing mechanism which(More)
