A study on PSK modulation schemes estimation with adapting to noise power based on a concept of software defined radio

摘要

Recently, the concept of software define radio (SDR) which has adaptability to variance of application and environment has been thoroughly investigated. Specially, there have been reports about the modulation scheme estimation algorithms which can be a key technique of SDR. One of the problems in the conventional modulation estimation algorithm is that the parameter of the estimation algorithm is not always optimum against the variance of CNR. Therefore, our proposed scheme can change the parameters of the blind modulation estimation algorithm to adapt the CNR by using blind noise power estimation algorithm.
