This paper describes a way to modify the K-Best Sphere Detector, using the knowledge that the real and the imaginary part of complex number are always orthogonal. To ensure that this property is used, a modification to the Real Value Decomposition is proposed that will ensure that the orthogonality is seen also after the decomposition. The proposed method allows for equally efficient implementations...
This paper introduces a parabolic synthesis methodology for developing approximations of unary functions like trigonometric functions and logarithms which are specialized for efficient hardware mapped VLSI design. The advantages with the methodology are, short critical path, fast computation and high throughput enabled by a high degree of architectural parallelism. The feasibility of the methodology...
Most of the power consumption has in the past been related to the dynamic activities, in a CMOS circuit. However, the static power, i.e. leakage, is a major contribution to the total power consumption, in present nano-meter scale technologies. This paper discusses static power reduction methodologies on architectural and arithmetical level. Novel arithmetic techniques to reduce the static power consumption...
