Abstract
A wireless communications device may include a wireless receiver receiving signals having alternating known and unknown symbol portions over a channel, and a demodulator systolic array. The demodulator systolic array may include a channel estimation module generating respective channel estimates for each unknown symbol portion based upon the known symbol portions. An autocorrelation module may generate autocorrelation matrices based upon the channel estimates. A channel match filter module may generate respective channel matching coefficients for the unknown symbol portions, and a factorization module may divide the autocorrelation matrices into respective upper and lower autocorrelation matrices. A transformation module may transform the channel matching coefficients into upper and lower channel matching coefficients. A back-substitution module may determine the unknown symbol portions by estimating the unknown symbol portions based upon autocorrelation matrices and channel matching coefficients, lower autocorrelation matrices and channel matching coefficients, and combining the estimates.
