Abstract :
An efficient zero-phase constrained frequency-domain block LMS adaptive algorithm, that has reduced computational complexity and fast convergence speed for highly correlated input signals is proposed. The algorithm is applied to narrowband interference rejection in direct-sequence spread spectrum systems and a simulation results is presented
