Lk. Hansen et Gh. Xu, A FAST SEQUENTIAL SOURCE SEPARATION ALGORITHM FOR DIGITAL COCHANNEL SIGNALS, IEEE signal processing letters, 4(2), 1997, pp. 58-61
We propose a fast sequential-estimation algorithm for separating multi
ple cochannel digital signals using an antenna array with unknown arra
y response. We present simulation results comparing speed and bit erro
r rate (BER) performance with an existing fast joint-estimation algori
thm, the iterative least squares with projection (ILSP) algorithm. The
new algorithm proves to be faster with only a modest degradation in B
ER. In addition, convergence speed is very robust with respect to addi
tive noise.
