- Abstract
- As a new type of a linear decorrelating receiver, the Pseudo-Decorrelator was
presented for asynchronous code division multiple access system by one of
authors. In this paper, the concept of the Pseudo-Decorrelator is extended to
derive a suboptimal receiver for WCDMA uplink systems in a Rayleigh fading
environment. Starting with the analysis of the multiple access components of
the decision statistics, a non-square cross-correlation matrix for each bit
is obtained. This cross-correlation matrix is then inverted and the inverted
matrix is applied to the decision statistics obtained from a conventional
receiver. Simulation results are presented for K-user systems over a Rayleigh
fading channel. The effects of the synchronization errors, such as time delays
and carrier phase errors, are also examined through simulations.
