Many wireless data communication systems such as LTE, and Wi-Fi, are
increasingly facing interference that is much stronger than thermal noise.
Interference may arise due to dense spatial reuse of spectrum intended
to increase user data rates, or from other devices emitting radiation
in the same spectrum, or from electronic circuitry within the communication
For a multi-antenna receiver operating in an interference-limited channel,
we evaluate four diversity combining algorithms in terms of outage
probability in the low-outage regime.
The contributions of this paper are
Our results can be applied in analyzing the outage performance and
throughput capacity of both centralized and decentralized
interference-limited wireless networks.
- derivation of closed-form expressions for the output
signal-to-interference ratio (SIR) statistics of fixed weight,
maximal ratio, selection and post-detection combining;
- comparison of the relative outage performance of these algorithms; and
- proposed diversity combining algorithms to reduce outage probability.
