    HI,
    Is anybody using 8-PSK modulation on the BCCH TRX?? There guys from ETSI clearly acknowledging, that using 8-PSK can affect neighbor cell measurement for MS in other cells.This is because of the fact that Time Slot using 8-PSK has generally 2-4dB lower power than the one using GMSK.

    Has anybody implemented 8-PSK on BCCH ans seen it’s impact ??

    We are using 8-PSK only on BCCH as this is the freq with less interference and no power control. The neighboring slots of the BCCH 1,7 are not using 8-PSK.
    We have no problems at this point.
    Where you saw this about ETSI. I have to check but I think Siemens recommend EDGE CU to be the BCCH one.

    Hi There,
    Well, here are the two links you can check…
    http://list.3gpp.org/scripts/wa.exe?A2=ind0209&L=3gpp_tsg_geran_wg1&D=0&T=0&P=466&D=1

    This one is a correspondence among 3GPP members . You can also check page 93 in Siemens Document titled GPRS/EGPRS Global Description.

    The next link discusses about EDGE in general

    http://www.commsdesign.com/design_corner/showArticle.jhtml?articleID=16505610. Unfortunately this link is down most of the time, but you can try.

    Ask how long it will be before you can go back to work or start regular exercise again. ,
