To accommodate information streams with different data rates over a direct-sequence
code-division multiple-access (DS-CDMA) network is
required due to a large variety of information sources, such as voice, data, and images.
This paper provides the novel adaptive blind estimating method for multi-rate
DS-CDMA signals. The underlying idea is to estimate the channel
and spatial signature by transforming them into one composite channel.
The composite channel is estimated with using linear constrained minimum variance
filtering and the method of Lagrange multiplies.
The simulation results show improvement of bit-error rate performance over the conventional detector
using subspace method and also confirm that the proposed method
is near-far resistant for both cases with and without inter-chip interference. |
