Abstract

In this paper blockwise decoded convolutional encoding is used and evaluated for the design of an error protection coding scheme matched with the characteristics of a variable-rate speech coder´s output bit-stream. The performance is evaluated for a symmetrical, interference limited, cellular system. Both microcellular and macrocellular propagation models are used. Different reuse factors are taken into consideration
