Analysis of Equal Gain Combining in Energy Detection for Cognitive Radio Over Nakagami Channels
Detection of spectrum holes in cognitive radio environment is a problem of significant interest. To best utilize the spectrum holes by secondary users, the detection of such spectrum holes quickly and accurately is of great importance. Mathematically speaking, achieving higher probability of detection with very low probability of false alarm by means of few number of samples is the objective of a secondary user system designer. Detection of a primary user while a secondary user experiences a deep fade is also expected and hence the detecting mechanism should be able to tolerate the low Signal to Noise Ratio (SNR) conditions.
