Detection Timing and Channel Selection for Periodic Spectrum Sensing in Cognitive Radio

Abstract: In this paper, detection timing and channel selection for periodic spectrum sensing are investigated to improve the performance of cognitive radio (CR) users. Designed to maximize the channel efficiency of CR users under a given level of interference with licensed users, the detection timing scheme utilizes the statistics of the licensed channel occupancy to determine the optimal starting point of each sensing action. A channel selection scheme in the multichannel multiuser environment is also proposed to specify which channel to detect for the upcoming sensing action based on detection timing. Numerical results demonstrate that our schemes considerably improve the overall channel efficiency while protecting the communication among licensed users.

A device, system and method for automatically configuring application terminals in home network

Abstract: A device, a system, and a method for automatically configuring application terminals in a home network are disclosed. The method is as follows. A home gateway receives identifier information of an application terminal sent by the application terminal through a Dynamic Host Configuration Protocol (DHCP). The identifier information of the application terminal is sent to a public network through a DHCP message, so as to determine a DHCP server corresponding to an automatic configuration server (ACS) of the application terminal. Address information of the ACS of the application terminal is obtained from the DHCP server on the public network through a DHCP message. The address information is transmitted to the application terminal, so that the application terminal obtains configuration information from the ACS according to the address information to perform an auto-configuration. Thus, a problem that the application terminal in a home network cannot directly obtain an ACS Universal Resource Locator (URL) through a DHCP message is solved, so that an auto-configuration of the application terminal is realized.

Abstract: In this paper, we describe the signal design for primary synchronization channel adopted for E-UTRA cellular system. By designing the signal to be centrally symmetric in the time-domain, the symmetric samples can be added prior to multiplication with the replica sample, thereby saving one multiplication per two received samples.

ITU-T EV-VBR: A robust 8-32 kbit/s scalable coder for error prone telecommunications channels

Abstract: This paper presents ITU-T Embedded Variable Bit-Rate (EV-VBR) codec being standardized by Question 9 of Study Group 16 (Q9/16) as recommendation G.718. The codec provides a scalable solution for compression of 16 kHz sampled speech and audio signals at rates between 8 kbit/s and 32 kbit/s, robust to significant rates of frame erasures or packet losses. It comprises 5 layers where higher layer bitstreams can be discarded without affecting the lower layer decoding. The core layer takes advantage of signal-classification based CELP encoding. The second layer reduces the coding error from the first layer by means of additional pitch contribution and another algebraic codebook. The higher layers encode the weighted error signal from lower layers using MDCT transform coding. Sev-eral technologies are used to encode the MDCT coefficients for best performance both for speech and music. The codec performance is demonstrated with selected results from ITU-T Characterization test.
