ETIN10 Kanalmodellering för trådlös kommunikation

2011/2012 Vt1

Errata

1. There is a mis-print in the statement of problem 25.5.3 (page 565). The correct statement should read: "A mobile communication system is to be designed to the following specifications: the instantaneous received amplitude r shall not drop below a specified level r_min more than 10% of the time. The system shall be operational at the cell-boundary (maximum distance from base station) for 90% of the time. The signal experiences both small-scale Rayleigh fading and large-scale log-normal fading, with σ_F=6 dB. Find the required fading margin for the system to work".   
2. In Appendix 7.A, in Table 7.1, the unit for distance should be 'km'.
3. In the third problem for Chapter 6, there is a small mistake for power delay profile. The right PDP for 55us to 65us should be  a₂e^{-b₂(tau-55*10^(-6))}
