The mean square error is time domain measure used to assess the speech quality. This objective measure can be used for discarding extra packets, only those packets may be discarded obtain the lowest MSE among all active users. This chapter is detailing the way this MSE can be utilized in STDM designs.STATISTICAL TIMEDIVISION MULTIPLEXING ARCHITECTU

The design of STOM based upon LPC envelope distance is used in simulation. The simulation based upon this criterion, performance of the SIDM is provided in this chapter. The quality of speech is measured subjectivelySTATISTICAL TIMEDIVISION MULTIPLEXING ARCHITECTURES AND DESIGN Editors Asadullah Shah Asadullah Shaikh MunibaShaikh ZeeshanBhatti Nuha

This paper presents a new technique for information hiding in Arabic language. The technique uses text steganography to hi de the information. Considering the existence of Harakat(Fatha, Kasra and Damma) in the languages a new approach of reversing the Fatha has been developed for message hiding.The technique has been also evaluated to ensure its q

Bahasa Melayu (Malay language) is a language spoken in Malaysia and many countries around it. It has rich literature and deep roots in culture. Bahasa Melayu language uses roman character set (i.e. A-Z) identical to English language. The written language uses the character set as building blocks to build word, sentences and phrases along with speci

Speech quality in multiplexing suffers due to various factors, including forced packet dropping. If a packet or segment ofspeech is dropped from any source by selecting users on random bases, and incidentally the randomly selected packet is perceptually sensitive, a single packet drop can cause a significant degradation is the quality both objectiv

Multiplexing techniques are broadly classified as analogue and digital, digital being the latest. Time Division Multiplexing (TDM) and Statistical TOM are most commonly used digital multiplexing techniques. The TOM is a detenninistic method of multiplexing various sources in pre-determined fixed slots. Statistical TDM, (STDM) uses dynamic method of

All communication networks use or going to use packet based communications that intrinsically use STDM for communication. No user is going to have a fixed time slot instead, a slot is allocated on a demand basis or activity basis. The packet discarding is a new' concept in networking, in this chapter a random packet discarding is explained.STAT

Linear Predictive Coding (LPC) envelop difference is a technique that exploits envelop of each frame. This is a frequency domain measure in which for each active speech frame and its reconstructed frame is used to find out the differences in their envelops. This LPC difference measures can be utilised for the STDM design purpose. This chapter is de

To design a STOM on the criterion of energies of each frame is one of the popUlar methods. In this each frames energy is calculated, a frame with lower energy is the best candidates among all users' speech frames. Dropping the frame with lmvest energy may degrade quality at its minimum as compared to the higher energy signals. This is also perc

A speech signal can be active or non-active; in one of the nvo states in anyone time, or for a frame of speech. The duration ofthe both active and non-active parts can varies based upon the modes of speech (monologue and dialogue). The activities or non-activities of the speech can be modelled by using Markov Model, in this scenario a two state mod
