Abstract:
The Orthogonal Frequency Division Multiplexing is one of the widely used modulation techniques in the present broadband wireless technology. The opportunities and challenges of this modulation technique are derived from its native advantages and disadvantages. One of the main problems is the high peak-to-average power ratio of transmission signal due to the superposition of many subcarriers. This paper presents a new hybrid peak-to-average power ratio reduction technique, which combines an active constellation extension method with a tone reservation method. The paper presents the performance and advantages of the mixed technique and compares it with other existing methods. The simulations shown that the proposed technique realizes an increased peak-to-average power ratio reduction compared to component methods with similar parameters.
