BACKGROUND [0003] The following description of related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section be used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of prior art. [0004] In general, a typical Fifth-Generation (5G) New Radio (NR) system includes a transmit chain(s) with a link budget such that a particular output power is radiated as per region- specific regulation norms. Higher transmit power than expected power may cause saturation of the power amplifier, leading to nonlinearities, overall signal degradation, and non-compliance with regional telecom regulatory laws. Similarly, low transmit power may lead to lower coverage and poor user experience.

In addition, the method includes filtering, by a processing module, valid DPD data samples from the DPD data samples. A DPD data sample is invalid if the transmit power or the feedback power is negative, infinity or zero, and the DPD data sample is valid if a difference between the transmit power and the feedback power is less than a maximum difference between the transmit power and the feedback power. The method includes analyzing, by the processing module, the valid DPD data samples to compare the transmit power against a first transmit threshold value and a second transmit threshold, and the feedback power against a first feedback threshold value and a second feedback threshold value.

[0008] In some embodiments, the method comprises determining whether the low transmit power alarm counter is greater than a second predefined threshold count for second predefined consecutive intervals and on determining that the low transmit power alarm counter is greater than the second predefined threshold count for the second predefined consecutive intervals, triggering a low transmit power alarm. [0009] In some embodiments, the method comprises, on detecting that DPD data samples in the captured DPD data samples are invalid for a first predefined consecutive time period, incrementing an invalid data counter, and determining whether a count in the invalid data counter is greater than a threshold invalid data count.
