Abstract

In this letter, the theoretical capacities of single-carrier and multi-carrier block transmission systems that employ narrowband interference avoidance are derived. It is shown that the capacity of an OFDM system that implements active interference cancellation is degraded by approximately one bit per second per Hz at high SNR when 10% of the band is nulled. In contrast, the capacity of a single-carrier system that uses envelope scaling in the time domain to create deep frequency notches is not significantly affected by the nulling process.
