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.
