I am not able to access android market through emulator.
No, because you must have the Market app to be able download apps from the Market, and it is not available in the emulator.
Android Market is not available through the emulator for similar reasons it is not available through the developer phone. Allowing people to buy applications with an unlocked phone (or the emulator) would make it easier for those paid apps to be redistributed as freee apps.
Will's right. But also see this if it helps: http://forum.openhandsetdevelopers.com/running-android-market-on-emulator-no-download-issue-t82.html
Check out this link.

You get a full featured market on your emulator. I don't know if it's legal(allowed by Google), but the image file, that this post mentions, is a link to HTC's download page.
I am able to access all the market apps now, right from the emulator, the paid ones, and the copy-protected ones also.
Cheers.
Dexter.
