Measurement of channel characteristic by bottom-up approach for indoor PLC channel

In this paper a comparison of delay spread, coherence bandwidth, root mean square delay spread and average delay estimated in both frequency bands 0.1-30 MHz and 0.1-100 MHz for indoor power-line communication network. The channel transfer function is computed via the application of transmission line theory. In this paper, it is shown that the 90th percentile of the coherence bandwidth at 0.9 correlation level is better for 100 MHz systems than the coherence bandwidth corresponding to 30 MHz systems. It is observed that as the number of bridge taps increases, it leads to decrease of the coherence bandwidth. In this paper, it is found that for two frequency bands the maximum excess delay increases as the number of bridge taps increases.
