Performance of Alamouti coding in real measured UHF channels

Abstract

The application of space-time/frequency coding is an interesting means to mitigate fading effects in terrestrial channels. Therefore, the well-known Alamouti scheme was introduced to the DVB-T2 standard. However, there have not been any measurements so far analysing the achievable gains using MIMO-schemes for broadcasting in UHF channels. Thus, extensive measurements have been performed. The obtained data was then used to feed a simulation chain for simulating the potential benefits of Alamouti coding in the measured channel. The created simulation results show significant gain for the application of Alamouti in DVB-T2.
