Performance Analysis of Low Density Parity Check Codes for Cognitive Radio
Error correcting coding is used to protect against errors introduced by transmission media. Error Correcting Code enables the communication systems to have a reliable transmission over noisy channels. Cognitive Radio is a creative technology proposed to increase spectrum usage by allowing cognitive users to use the unused spectrum in changing environments. During the spectrum allocation for Primary user and cognitive user, lot of information may be lost due to burst errors and power issues. In this paper, we will describe the performance of LDPC codes for cognitive Radio.
