this paper presents a full duplex, real time implementation of itu-t g.723.1 [7,8] speech coder using the tms320c5402 dsp chip which is based on a 16 bit fixed-point architecture. an optimization method is proposed in order to reduce the total necessary cycle time consumed in real-time implementation. the multi-pulse maximum likelihood quantization (mp-mlq) excitation search block which is the ...

In this short note, we discuss the circumstances that can lead to a failure observe design order of discretization error convergence in accuracy verification when solving time-dependent problem. particular, problem failing spatial with an extremely small time step. The same is encountered even if step reduced grid refinement. These cause serious because then one would wind up trying find coding...
