Abstract— We propose a simple speech compression algorithm
using subband division and ADPCM (Adaptive Differential
Pulse Code Modulation) algorithm. Although speech data are
stored in a semiconductor memory device, its capacity and the
available network capacity are limited. Therefore, it is necessary to
compress the data as much as possible. The first is that the
reconstructed datum must be understood correctly. Speech signal is
compressed with a ratio of 1/4 using the proposed subband division
and ADPCM (Adaptive Differential Pulse Code
Modulation) algorithm.

mobilecommunication
In this paper the reduction of Intersymbol Interference
(1 ) in mobile communication channels is addressed. A
well known technique for IS1 reduction is adaptive equalization
in which the time-varying characteristics of the mobile
channel is tracked by an adaptive algorithm. We compare
different adaptive strategies and equalizer structures with
respect to overall system performance in terms of computational
complexity, numerical stability, finite wordlength
effects, size and power consumption required for VLSI implementation.
