    • The disclosed subject matter relates to communicatively coupled cognitive radio systems, devices, and methodologies facilitating utilization by secondary users of portions of spectral bands unused by primarily users. This utilization can be achieved by cooperative spectrum sensing employing ST coding and/or SF coding for transmit diversity. Further, cooperative spectrum sensing can be improved by employing relay diversity with or without algebraic coding. A threshold probability of false alarm can be reduced by applying transmit diversity with space time coding and/or space frequency coding. Further, relay diversity can be employed to compensate for reduced sensing diversity order were some nodes in a cooperative spectrum sensing system cannot report directly. Algebraic coding can be combined with relay diversity to decrease the threshold probability of false alarm in relay diversity systems while maintaining high levels of sensing diversity order.
    • 所公开的主题涉及通信地耦合的认知无线电系统,设备和方法,其帮助次要用户利用主要用户未使用的频谱带的部分。 这种利用可以通过使用ST编码和/或用于发射分集的SF编码的协作频谱感测来实现。 此外,通过采用或不采用代数编码的中继分集,可以改善协作频谱感测。 通过应用具有空时编码和/或空间频率编码的发射分集,可以减少虚警的阈值概率。 此外,可以采用中继分集来补偿协作频谱感测系统中的一些节点不能直接报告的降低的感测分集顺序。 代数编码可以与中继分集相结合,以降低中继分集系统中虚警的阈值概率,同时保持高水平的传感分集顺序。
