Performance Comparisons of NBI Suppression Techniques
In Section 7.4, we have
derived closed-form expressions for the performance measure (SINR) of the linear
MMSE detector against three types of NBI. In this section we compare its
performance against NBI with performance bounds for the linear and nonlinear NBI
suppression methods discussed in Sections 7.2 and 7.3.
7.5.1 Matched Filter
For the conventional detector, the received signal r in (7.67) is sent directly to a
single filter matched to the spreading sequence (i.e., w = s). The
mean and variance at the output of the matched filter are
Equation 7.119
Equation 7.120
The output SINR is then given by
Equation 7.121
