Abstract:
1. A method for determining a hermetian of a system response matrix for use estimating data of a plurality of transmitted data signal, the method comprising: providing channel codes and channel responses, the channel codes being a combination of a real spreading code, a complex scrambling code and a sign of a channel code specific multipler, the channel code specific multipliers having real and imaginary values; determining real and imaginary components of an approximate hermetian system response matrix using the channel codes and the channel responses; and applying a real/imaginary aspect of the channel code specific multiplier to the real and imaginary components of the approximate hermetian of the system response matrix to derive the hermetian of the system response matrix; and estimating the data of the plurality of transmitted data signals using a received vector corresponding to the plurality of transmitted data signal and the hermetian of the system response matrix.
