Abstract :
We show that block coded sequences are cycloergodic, and based on this property, we introduce a new nonprobabilistic formula to calculate the average power spectral density of these sequences. We present a new sufficient condition to construct codes with an arbitrarily high-order spectral-null at zero frequency. Given this condition, we outline two new coding schemes and use them to generate new classes of efficient high-order spectral-null sequences
