Abstract
This paper outlines a procedure to extend, or
upsample, the ITU power delay profiles (PDP) to improve the
frequency correlation properties while keeping the same mean
delay and almost the same rms delay spread. Realistic frequency
correlation properties are of particular importance for the
evaluation of wideband system concepts with frequency
dependent characteristics, e.g. frequency domain link adaptation
and packet scheduling, both of which are likely to be part of
future wideband systems such as based on OFDM. With the
suggested procedure the frequency correlation can be kept
approximately at or below 0.6 for frequency separations up to
25 MHz for the exemplified ITU Vehicular A and Pedestrian B
channel profiles. The compatibility in terms of link level
performance with WCDMA rake processing and the
representation of the profiles on different sampling grids is
briefly discussed in the paper.
