Speech enhancement for mobile telephony [PDF]
IEEE Transactions on Vehicular Technology, 1990 The properties of noise fields in automobile interiors are discussed with a view toward speech enhancement for voice-activated mobile telephony. The limitations on performance of adaptive noise cancellation are explained in the context of the spatial correlation properties of the noise field.

Merger Simulation in Mobile Telephony in Portugal [PDF]
SSRN Electronic Journal, 2006 This article assesses the unilateral effects on prices of a merger in the Portuguese mobile telephony market. We use aggregate quarterly data from 1999 to 2005 and a nested logit model to estimate the price elasticities of demand and the marginal costs of subscription of mobile telephony. Given these estimates, we simulate the effects of the merger. We

Diffusion of digital mobile telephony: Are developing countries different? [PDF]
Telecommunications Policy, 2005 Factors determining the diffusion of digital mobile telephony across developed and developing countries are studied with the aid of a Gompertz model. After controlling for other factors, the speed of diffusion per se is not significantly different between the two groups of countries.

Mobile Internet telephony protocol: an application layer protocol for mobile Internet telephony services [PDF]
1999 IEEE International Conference on Communications (Cat. No. 99CH36311), 2003 Internet telephony realizes the transmission of two-way, real-time, synchronous traffic over IP-based networks. Mobile Internet telephony introduces mobility to Internet telephony, allowing one to stay in communications while roaming. In this paper, a novel protocol called mobile Internet telephony protocol (MITP) is proposed.
