burst is received from the receiver step 905 if all bursts have been processed u201c yes u201d path out of decision step 928 then the toa is determined using the results of the ici step 930 fig1 and 11 respectively illustrate the toa performance using the apparatus illustrated in fig8 for a channel which experiences awgn and cci by comparing fig1 and 11 with fig6 and 7 the improvement using the modified ici algorithm in accordance with the present invention can be seen in fact by comparing the fig1 and 11 with fig1 and 2 it can be seen that the modified version of the ici algorithm in accordance with the present invention in an environment where gsm and edge signals co exist results in almost the same performance as in the gsm or edge only case where a loss of about 1 db only can be observed it should be noted that no detection of the modulation format is necessary although the present invention has been described above in connection with a gsm receiver the present invention is equally applicable to a edge receiver in case of an edge receiver rotator unit 820 would perform a derotation of u2212 u03c0 8 the remainder of the processing would be performed in accordance with the description above it should be noted that exemplary methods of the present invention are not limited to application described above the present invention.
