“…This scheme has been widely adopted in many CDMA systems [2]. In many previous works, authors focused on analyzing BER and PER performance of SSPC in different transmission environments, [3] and [4], or evaluating power spectrum density (PSD) of PCE, [5] and [6], which have shown a great impact on the performance of SSPC. However, few authors proposed a method to calculate PCE which dominates the performance of SSPC.…”

The analysis regarding the impact of the single-step power control (SSPC) scheme on the system performance such as bit error rate, packet error rate, and queueing variation is hard to access. In this work, we propose an approach to analyze that impact when being in finite state Markov channel (FSMC). To achieve the understanding of the relationship between SSPC, FSMC, and the queueing variation, power control error (PCE), error rate, and the PDF of queueing length are first calculated. PCE variation is modelled, which then benefits the evaluation of packet error rate (PER) and bit error rate (BER). Furthermore, based on these analysis, a SSPC model is proposed to simplify the overall system. The behavior of SSPC in FSMC can be better understood with the help of the proposed SSPC model. Simulation results have shown the validation of the proposed PCE variation model and SSPC model.
