WebSecondly, a variable forgetting factor RLS (VFF-RLS) algorithm instead of the conventional RLS is used to estimate the time-varying channel impulse response (CIR). Experimental results show that improved performance can be achieved by proposed receiver with the VFF-RLS algorithm compared to that of receiver with the conventional … Recursive least squares (RLS) is an adaptive filter algorithm that recursively finds the coefficients that minimize a weighted linear least squares cost function relating to the input signals. This approach is in contrast to other algorithms such as the least mean squares (LMS) that aim to reduce the mean square error. In the … See more RLS was discovered by Gauss but lay unused or ignored until 1950 when Plackett rediscovered the original work of Gauss from 1821. In general, the RLS can be used to solve any problem that can be solved by See more The idea behind RLS filters is to minimize a cost function $${\displaystyle C}$$ by appropriately selecting the filter coefficients See more The lattice recursive least squares adaptive filter is related to the standard RLS except that it requires fewer arithmetic operations (order N).
