“…i.e., the noise power and the noise-plus-primary-signal power are not distinguished. NP-TDSC is robust against noise uncertainty, but even with exact noise power, it suffers from considerable performance loss compared to the perfect ED as shown in [14].…”

“…In [12][13][14][15], intended at sensing signals such as DVB-T2 signals, correlation-based detectors were proposed by exploiting correlation cyclic prefix or pilot. The exact noise power in these detectors are replaced with the power of received signal which is impracticable because the received signal is highly likely to contain the PUs signals.…”

“…Owing to the European analogue switch-off and increasing scarcity of spectrum, DVB drew up commercial requirements for a more spectrum-efficient and updated standard. DVB-T2 easily fulfils these requirements, including increased capacity and the ability to reuse existing reception antennas [14]. From a spectrum sensing point of view, important DVB-T2 parameters are represented by: channel bandwidth (that ranges from 1.7 to 10 MHz), the OFDM Cyclic Prefix (CP) length (that ranges from 1/128 to 1/4 of the OFDM symbol length), and the presence of OFDM pilots (continual and scattered).…”

The demand for wireless connectivity is increasing exponentially resulting in an unprecedented demand on the limited radio spectrum. Due to the current fixed spectrum licensing scheme, it is becoming increasingly arduous to find extra spectrum resulting in a paradigm shift towards efficient utilization of radio spectrum in order to address the spectrum scarcity. The transition from analogue to digital terrestrial television has freed-up some spectrum thereby creating unique opportunities for exploitation of locally underused portions of the TV bands referred to as TV white spaces (TVWS) and their exploitation offers an attractive way of making efficient use of radio spectrum as long as the secondary users do not interfere with the primary users. This is enabled by employing cognitive radio technology that allows for dynamic spectrum access. This paper investigates the aspect of interference in TV White spaces and the possibility of mutual coexistence between primary users and secondary users operating in TV White spaces. The impact of interfering signals is undertaken to show the probability of interference in both same channel and different adjacent channels scenarios. The interference analysis is carried out using the SEAMCAT simulation software. Simulation results show that in a power limited secondary network, vacation of cognitive users from active spectrum bands is crucial for ensuring coexistence. The various interference mitigation mechanisms employed by CR networks are also reviewed. In TV white spaces, mitigating interference is vital not only for primary user protection, but also for ensuring the quality of service of the secondary users.
