Signal processing arrangement and signal processing method |
摘要 |
A signal processing arrangement is designed to process a digitalized phase-modulated and/or digitalized spreaded input signal (1) and has a complex channelizer (2) which despreads and/or demodulates the input signal (1) in the time range on the basis of a folding operation. |

1. A signal processing device for a radio locking system to process at least one of a digitized phase-modulated and digitized spread input signal including a complex channelizer configured to perform at least one of despreading and demodulating the input signal in the time domain using a convolution operation, the complex channelizer comprising:
a sampler configured to receive the digitized input signal and sample the received digitized input signal during a defined time period; a first window function configured to weight the input signal samples using a first multiplier; a buffer storage downstream of the first window function and configured to buffer the weighted input signal samples; a multiplication function configured to receive the weighted input signal samples from the buffer storage and apply a second multiplier to shift the frequency of the input signal samples to baseband; and a low-pass filter downstream of the multiplier and configured to receive the baseband signals, distinguish the signals into different frequency subranges, and filter out one or more of the distinguished subranges; wherein the filter implements a convolution with a filter impulse response. |
