摘要：The disclosed subject matter relates to communicatively coupled cognitiveradio systems, devices, and methodologies facilitating utilization by secondary users ofportions of spectral bands unused by primarily users. This utilization can be achieved bycooperative spectrum sensing employing ST coding and/or SF coding for transmitdiversity. Further, cooperative spectrum sensing can be improved by employing relaydiversity with or without algebraic coding. A threshold probability of false alarm can bereduced by applying transmit diversity with space time coding and/or space frequencycoding. Further, relay diversity can be employed to compensate for reduced sensingdiversity order were some nodes in a cooperative spectrum sensing system cannotreport directly. Algebraic coding can be combined with relay diversity to decrease thethreshold probability of false alarm in relay diversity systems while maintaining highlevels of sensing diversity order.
