hi adnan,

1. First stack the multispectral bands except the thermal (band 6) and panchromatic (Band 8).

In your case may be 1, 2, 3, 4

Using ERDAS: Image Interpreter ->Utilities->Layer Stack

Now you have one multistektral image with 30 m and panchromatic (in Landsat ETM Band 8 ) with 15 m.

2. Fusion the stacked image with panchromatic

ERDAS: Image Interpreter -> Spatial Enhancement -> Resolution Merge

Select high resolution input as panchromatic image

Multispectral as stacked image

There are several chose for methods you can tray which one more suitable

I hope it will help
