Efficient algorithms in speech coding

The need for low complexity speech coding algorithms has emerged due to application driven requirements. This may be attributed to the power consumption constraints placed on hand held mobile communication systems and the Electromagnetic Interference emission requirements placed on aU telecommunication products for both home and office use. Electromagnetic Interference emissions are hardware design specific and become prevalent when faster rated hardware is used. Low complexity speech coding algorithms can be implemented on slower DSP processors, thereby making it easier to meet the emission requirements. Slower DSP processors consume less power than faster processors.
