To satisfy energy and complexity constraints, embedded wireless systems require fixed-point arithmetic implementation. To optimize the fixed-point specification, existing approaches are based on fixed-point simulations to evaluate the performances. In this paper, the approach used to optimize the fixed-point specification for a WCDMA receiver is presented. The dynamic range and the fixed-point accuracy...
In disaster areas, a high demand of call requests initiated by people in such areas is sent to mobile networks because they might need to use emergency services or inform their families, friends about their current situation. In this paper, we introduce an emergency multi-system access (EMSA) which utilizes WCDMA networks and exploits a mechanism of selecting proper base station (SPBS). In the emergency...
One of the most important applications of digital signal processing (DSP) is wireless communication. This kind of application requires low power implementation of DSP, which generally uses fixed-point arithmetic. The fixed-point architectures should be developed to maintain the energy consumption power at a reasonable level. In this paper, an approach which adapts the fixed-point specification according...
