Abstract :
A methodology of mixed-tone recursive least squares algorithm development based on an orthogonal projection approach is presented for per-tone equalisation in discrete multitone systems. A mixed-tone cost function described as the sum of weight-estimated errors is minimised to achieve the solutions for different per-tone equalisers simultaneously. Simulation results reveal improvement of achievable bit rate and signal to noise ratio performance as compared to the PTEQ exploiting conventional RLS algorithm.
