“…In these two schemes high data transfer rates could be achieved, but the polar pulses contain many harmonics, which will lead to a high BER. Boloursaz et al [19] reduced the BER by repeating coding and clustering, but resulted in a lower data transmission rate.…”

A universal technique for transmitting data over voice (DoV) links that can be applied to various cellular networks is proposed. In the scheme, a generic modulation model is established based on waveform symbol mapping, where the data to be transmitted are mapped into finite waveform symbols of a codebook generated offline and demodulated with soft decision results at the receiving end. To make the proposed scheme applicable to various kinds of cellular networks, first sinusoidal signals are selected to synthesise waveform symbols due to their stable transmission characteristics over various voice channels. Then, an analytical method based on Surface Packing is proposed to optimise modulation codebooks. Finally, the target demodulation codebook is obtained through learning from the modulation codebook online. Simulation results show that the proposed scheme performs well over voice channels with different vocoders and has low symbol error rate on various vocoders. Compared with previous schemes designed for some specific vocoders in global system for mobile communication (GSM), the proposed scheme can extend the application scope of DoV to cross‐network scenarios consisting of GSM, universal mobile telecommunications system (UMTS) and long‐term evolution (LTE).

“…Thus, in this approach, symbol rate is , where represents the number of samples devoted to each symbol. For each symbol rate, appropriate statistically efficient speech like symbols are transmitted through the channel [3], [8]. Simulations of GSM FR and HR speech codec are performed with the C library from [12].…”

“…This approach achieved a raw data rate of 3kbps with 2.9% Bit Error Rate (BER) on the GSM Enhanced Full Rate (EFR) voice channel. A similar method is utilized by [7] and [8] for data communication through codecs that apply Algebraic Code Excited Linear Prediction (ACELP) speech coding technique. This approach modulates the input data stream on algebraic codebook pulse positions making a PPM signal.…”

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.

“…As classified by [3, 4], prior researches on data transmission over voice channels have proposed three different approaches of ‘parameter mapping’ [15], ‘codebook optimisation’ [16–18] and ‘modulation optimisation’ [19, 20] to overcome voice channel non‐idealities [3, 4, 21]. These approaches are well compared in [4].…”

The common voice channels existing in cellular communication networks provide reliable, ubiquitously available and top priority communication mediums. These properties make voice dedicated channels an ideal choice for high priority, real time communication. However, such channels include voice codecs that hamper the data flow by compressing the waveforms prior to transmission. This study designs codebooks of speech-like symbols for reliable data transfer through the voice channel of cellular networks. An efficient algorithm is proposed to select proper codebook symbols from a database of natural speech to optimise a desired objective. Two variants of this codebook optimisation algorithm are presented: One variant minimises the symbol error rate and the other maximises the capacity achievable by the codebook. It is shown both analytically and by the simulation results that under certain circumstances, these two objective functions reach the same performance. Simulation results also show that the proposed codebook optimisation algorithm achieves higher data rates and lower symbol error rates compared with previously reported results while requiring lower computational complexity for codebook optimisation. The Gilbert-Elliot channel model is utilised to study the effects of adaptive compression rate adjustment of the vocoder on overall voice channel capacity. Finally, practical implementation issues are addressed.
