In cognitive radio context, the parameters of coding schemes are unknown at the receiver. The design of an intelligent receiver is then essential to blindly identify these parameters from the received data. The blind identification of code word length has already been extensively studied in the case of binary error-correcting codes. Here, we are interested in non-binary codes where a noisy...
In the cognitive radio field, the receiver should be able to perform a blind identification of the encoder parameters used by the transmitter from the only knowledge of the received data stream. In this context, the most methods dedicated to the blind identification of the parameters of error correcting codes are based on the rank calculation of matrices formed from the received data stream. Nevertheless,...
In most digital communication systems, error correcting codes are essential to achieve good immunity to channel impairment. Due to the complexity of the encoding process, but especially of the decoding process, most research on error correcting codes is restricted to binary data which are elements of the Galois field GF(2). Reed Solomon codes have been the most commonly used so far as non-binary (GF(q))...
In order to enhance the reliability of digital transmissions, error correcting codes are used in every digital communication system. To meet the new constraints of data rate or reliability, new coding schemes are currently being developed. Therefore, digital communication systems are in perpetual evolution and it is becoming very difficult to remain compatible with all standards used. A cognitive...
