ABSTRACT:
A hermetian of a system response matrix is to be determined. Spreading codes, channel specific multipliers and channel impulse responses are provided. The channel code specific multipliers have real and imaginary values. Channel codes being a combination of a real spreading code, a complex scrambling code and a sign of the channel code specific multiplier. Real and imaginary components of an approximate hermetian of the system response matrix are determined. The channel code specific multipliers are applied to the real and imaginary components of a result of the convolutions to derive the hermetian of the system response matrix.
