    Adaptive Two-stage Spectrum Sensing under Noise Uncertainty in Cognitive Radio Networks 

    Kornkamol Thakulsukannant; Wilaiporn Lee; Akara Prayote; Kanabadee Srisomboon (2016)

    To utilize licensed spectrum bands efficiently, spectrum sensing needs to be accurate and fast. The occurrence of noise uncertainty and the lower in received PU signal power due to the distance between the transmitter and the receiver, path loss, are the main challenges that has a great impact on the accuracy of spectrum sensing. In this paper, we propose a new scheme of two-stage spectrum sensing, “Adaptive Two-stage Spectrum Sensing (ATSS)”, under noise uncertainty environment. ATSS is a modified of a conventional two-stage spectrum sensing ...

    Corporate Governance, Violations and Market Reactions 

    Visit Phunnarungsi (2013)

    We test the relation between firm-level corporate governance and the market reaction to announcements of violations of rules and regulations by Thai listed firms. We find no significant difference in market reaction when firms with high and low governance scores commit violations. We do find a larger negative abnormal return when firms with low past violation records violate the rules. The market reaction is especially strong, − 8.1% on average, when firms with low past violations and low governance scores commit violations. The evidence suggests ...
