    Fixed-Point MAP Decoding of Channel Codes

    This paper describes the fixed-point model of the maximum a posteriori (MAP) decoding algorithm of turbo and low-density parity-check (LDPC) codes, the most advanced channel codes adopted by modern communicati...

    Latency-Sensitive High-Level Synthesis for Multiple Word-Length DSP Design

    High-level synthesis (HLS) currently seems to be an interesting process to reduce the design time substantially. HLS tools actually map algorithms to architectures. Conventional HLS techniques usually focus on...

    Complexity-Aware Quantization and Lightweight VLSI Implementation of FIR Filters

    The coefficient values and number representations of digital FIR filters have significant impacts on the complexity of their VLSI realizations and thus on the system cost and performance. So, making a good tra...

    Sensitivity-Based Pole and Input-Output Errors of Linear Filters as Indicators of the Implementation Deterioration in Fixed-Point Context

    Input-output or poles sensitivity is widely used to evaluate the resilience of a filter realization to coefficients quantization in an FWL implementation process. However, these measures do not exactly conside...
