Estimating the number of interferers and their respective channel order is useful for several applications such as the excision of multi-interferer radio frequency interference (RFI) and the mitigation of narrowband interferers prevalent in ultra-wideband communications. For single-input multiple-output systems suffering from multi-interferer RFI, we propose a matrix-based joint enumerator algorithm and its smoothed version to estimate the number of interferers and their respective channel order. Simulations corroborate the joint enumeration capability of the proposed algorithms and an improved performance of the smoothed enumerator which demands higher computation time.
