  Pseudorandom PSK [1] enables parallel communication on the same carrier
frequency and at the same time. We propose different signal processing methods
to receive data modulated with pseudorandom PSK. This includes correlation with
the carrier frequency which can be applied to signals in the kHz to MHz range
and signal processing in the intermediate frequency where the correlation with
the carrier frequency is performed analogous in the RF front end. We analyze
the computation complexity for signal processing with the parameters of symbol
length $T$ and number of repetitions of each symbol $K$ with pseudorandom PSK
and show that the number of operations for each sampling point is
$\Theta\left(K\right)$.
