Abstract
Wireless wideband communication systems provide high data transmission rates suitable for fast Internet access. This paper presents a modulation scheme for Local Multipoint Distribution Service (LMDS), which improves coverage under rainy weather conditions. Following a comparison of a number of modulation schemes with a 26 GHz carrier, a 16-QAM system is found to offer good compromise between coverage and receiver structure complexity. The effects of rain attenuation increase with carrier frequency. System performance varies significantly depending on whether the system is operated on a dry day or under heavy rain.
