Multi-Level Modulation in the Indoors Leaky Feeder Environment
Leaky feeders offer the prospect of high. average Signal to Noise Ratio (SNR) in an indoors environment. The signal is transmitted from a series of slots acting as antennae and superposition of the paths results in fades of up to 25 dB below the mean signal level. A model is presented for the propagation path between the leaky feeder Base Station (BS) antenna and a single omni-directional receiver antenna, which was verified using measurements. The Bit Error Rate (BER) performance of such a system is investigated for I, 2 and 4 bits per symbol, coherent and non-coherent modulation schemes. These are compared with the performance of a more conventional indoor BS antenna.

Abstract

Leaky feeders offer the prospect of high. average Signal to Noise Ratio (SNR) in an indoors environment. The signal is transmitted from a series of slots acting as antennae and superposition of the paths results in fades of up to 25 dB below the mean signal level. A model is presented for the propagation path between the leaky feeder Base Station (BS) antenna and a single omni-directional receiver antenna, which was verified using measurements. The Bit Error Rate (BER) performance of such a system is investigated for I, 2 and 4 bits per symbol, coherent and non-coherent modulation schemes. These are compared with the performance of a more conventional indoor BS antenna.
