Measurement of relative phase for 5G NR digitally modulated signal using cumulative distribution function
Abstract This letter proposes a measurement technique for the relative phase of a 5G new radio (NR) signal. The total radiated power (TRP) is measured to evaluate wireless equipment. However, this cannot be implemented using the near‐field measurement system owing to the digitally modulated signal....

| description | Abstract This letter proposes a measurement technique for the relative phase of a 5G new radio (NR) signal. The total radiated power (TRP) is measured to evaluate wireless equipment. However, this cannot be implemented using the near‐field measurement system owing to the digitally modulated signal. The relative phase detected by using a vector network analyser (VNA) changes significantly owing to the fast change in the signal in the time domain and the imperfect synchronisation of internal receivers of VNA. This study calculated the cumulative distribution function and medium value for the signal from the multi‐probe measurement system. The detected phase agreed well with the exact value obtained from the continuous wave signal. The proposed technique can be used for TRP calculations using the near‐to‐far field transformation. |
