Research on symbol rate estimation based on the generalized square envelope spectrum

In order to solve the problem that the symbol rate estimation algorithm based on square envelope spectrum will significantly degrade in alpha stable distribution noise, square envelope spectrum was extended, and the new concept of generalized square envelope spectrum was put forward. On this basis, the corresponding relationship between symbol rate and pulse line in the generalized square envelope spectrum were analyzed. Finally the symbol rate was estimated indirectly by measuring pulse line. Simulation results show that the performance of this method have good performance both in the Alpha-stable distribution noise and the Gaussian noise.
