Interference cancellation for shot-code DS-CDMA in the presence of channel fading

Creator:

Dutta, Amit K.

Abstract:

Interference from other adjacent users in wireless applications is a major problem in direct-sequence code-division multiple-access (DS-CDMA). This is also known as the near-far problem where a strong signal from one user interferes with other users. The current approach to deal with the near-far problem in DS-CDMA systems is to...

Dissertation
Adaptive dual-loop algorithm for cancellation of time-varying offsets in direct conversion mixers

Creator:

Holenstein, Christian

Abstract:

The thesis presents a new algorithm and structure that is to be used in conjunction with a specially modified CMOS Gilbert cell mixer to remove time-varying DC offsets in direct conversion receivers. In our approach, the DC offset is detected at the output of the mixer using a dedicated coarse...
