Capacity in Wideband Code Multiple Access
(WCDMA) systems is interference limited, it is also strongly
linked with coverage. The greater the level of influx of users
within the cell, the higher the interference and hence the
lower the cell coverage becomes and vice versa. This is
called Cell Breathing. In this paper a Walsh coding is used
as a precoding stage to the Multiple-Input Multiple OutputOrthogonal
Frequency Division Multiplexing (MIMOOFDM)
system. The results of this work are compared with
a conventional work that is based on convolutional coding.
This is in order to check its fitness to the current system
structure and the enhancement of the EblN., which will
directly result in a better cell coverage and continued
reliable services for the area of the cell as the load increases.
