Abstract

In this paper the results of the interference analysis in FS‐ML due to new WLL systems with broadband SSDS‐CDMA techniques, sharing the same frequency band, is evaluated. Effects of WLL systems are expressed through the interference noise power at the FDM/FM receiver and BER at the DML receiver output, respectively. The results obtained show that in the typical working conditions with careful cell planning, interference can be neglected, and in most situations WLL overlay would not cause excessive interference in the FS‐ML. This conclusion is of great importance for the development of telecommunication systems, specially in rural areas, because it is possible to develop telecommunication systems fast and economically, without any additional frequency demands and under favourable economical conditions.
