Power consumption is the most important issue in circuit design nowadays, and clock gating is the most widely used technique to reduce the dynamic power at register transfer level. The traditional clock gating style using an XOR gate to generate a gated clock was proposed but has not been well studied. It can be extended to multiple flip-flops easily but the power performance is not optimal. In this...
The authors evaluate the improved energy and spectral efficiency by pilot overhead reduction of turbo coded orthogonal frequency division multiplexing (OFDM) systems employing an iterative phase estimation algorithm. Developed from the recently proposed iterative phase estimation schemes, the phase estimation and compensation process is embedded into the basic iterative turbo decoding process for...
