The communication needs of Earth observation satellites is steadily increasing. Within a few
years, the data rate of such satellites will exceed 1 Gbps, the angular resolution of sensors will be
less than 1 μrad, and the memory size of onboard data recorders will be beyond 1 Tbytes.
Compared to radio frequency links, optical communications in space offer various advantages
such as smaller and lighter equipment, higher data rates, limited risk of interference with other
communications systems, and the effective use of freque ....etc

Abstract
This paper presents a sufficiently low bit rate Hi-Fi
audio coding technique with low computation designed
for transmitting real-time high-quality audio signal over
wireless channel. This technique applies wavelet packet
transform to decompose audio signal into subbands to
eliminate redundant data using spectral and temporal
masking properties. The encoded audio data is framed
with some critical field is protected by channel coding to
improve noise immunity when frames are transmitted
wirelessly. Experimental results s ....etc

This article describes about wavelet packet (WP) filterbank.Most effective means of improving the auditory receptive abilities of people with profound hearing loss is cochlear implants(CI).Current cochlear implants consist of a microphone, a speech processor, a transmitter, a receiver and an electrode array which is positioned inside the cochlea.For decomposintion of input audio signal into different frequency bands and delivering the most appropriate stimulation pattern to the electrodes,speech processors are used.The bandwidths of the freque ....etc
