Abstract. In this study, an analytical formula for multipleinput single-output single frequency network gain (MISO-SFNG) is investigated. To formulate the net MISO-SFNG, we derived the average signal to interference plus noise ratio (SINR) where the gain achieved by the distributed MISO diversity as a function of power imbalance is curve-fitted. Further, we analyzed the losses owing to self-interferences resulting from the delay spread and imperfect channel estimation. We verified the accuracy and effectiveness of the derived formula by comparing the measurement results with the analytical results. The derived formula helps to understand how various system factors affect the gain under a given condition. The formula can be used to evaluate the MISO-SFNG and to predict the MISO-SFN coverage in various system configurations.

“…In [5], an analysis of the effects of time-based pilot interpolation over time-varying channels is presented. Using different pilot patterns, a DVB-T2 channel estimator and an equalizer were modeled and evaluated in terms of performance in [6] and [7]. Also, an in-depth study of minimizing the number of the used pilots in terms of error probability can be found in [8].…”

In DVB-T2 broadcasting applications, errors occur due to channel imperfections, reducing the system's throughput. The use of a channel estimator and equalizer counteracts the channel induced distortions and thus improves the system's Bit Error Rate (BER). In our study, a simple-to-implement channel estimator is proposed. It is based on averaging the sub-channel frequency responses of successive OFDM symbols in time, considering a very slow time-varying channel. In the frequency domain, spline interpolation is applied. The proposed estimator can be used in practical receivers with limited computation power and low memory capacity.
