Global System for Mobile communications (GSM) is a widely spread, reliable and P2P channel through all over the world. These characteristics make GSM a channel suitable for a variety of applications in different domains especially security applications such as secure voice communication. Performance and usage of GSM applications extremely depends on the transmission data rate. Hence, transmitting data over GSM is still an attractive topic for research. This paper considers the problem of digital data transmission through the GSM voice channel. A lower capacity bound for data transmission through the GSM Adaptive Multi Rate (AMR) voice codec is presented. The GSM channel is modeled in a simple manner to overcome it's memory and non-linearity effects. A new statistic based on received samples is extracted and a novel method to transmit data over that channel which asymptotically tends to the achieved lower bound is offered.

ABSTRACT:In this paper, a novel codebook design method for data modem over voice channel is presented. Proposed method searches the symbols which have the maximum probability distribution overlap in the symbol space and minimizes the overlap to improve the symbol error rate via minimax optimization. We present numerical simulations and an example implementation. We also give the results of the experiment tests.

In this paper, performance of MFSK (M-ary Frequency Shift Keying) modulation scheme for data transmission over GSM (Global System for Mobile Communication) voice channel is evaluated. The performance is analyzed in terms of bit error rate (BER). This evaluation is done to determine M order that will be chosed for application on data transmission over GSM voice channel. On the simulation process, data are encoded into symbols and modulated using MFSK modulator become speech like waveform. The voice than coded using CELP (Code Excited Linear Prediction) algorithm, and sent over the air that modelled as AWGN (Additive White Gaussian Noise) channel. At the receiver side, the received speech like signal are demodulated and converted back to data. From the simulation using fix signal to noise ratio (Eb/No= 6 dB), we achieved a bit rate of 2.5 kbps with BER 2.01 × 10 −3 for M=4, 2.22 × 10 −3 for M=8, and 1.87 × 10 −3 for M=16.
