The Long-Term Evolution broadband will become the dominant technology for the next generation of communication systems. Its performances in terms of capacity and error rate are studying for rural and urban environment. However, even if this is a special case, tunnel environment is often encountered. The objective of this paper is to predict the error rate by using software simulating the proposed LTE data processing and by introducing, in this software, channel transfer functions measured in tunnels. Among all possible transmission modes, emphasis is on the transmit diversity schemes. After a brief description of the channel characteristics and of the simulation process, improvement brought by the possible configurations of transmit diversity is studied, the frequency band being around 3.4 GHz. |
