Abstract :
In OFDM PMEPR coding, the existing construction method for Asterisk 16QAM is based on the set sum of two QPSKs. However, this approach needs the quaternary Reed-Muller codes in implementation. The high complexity of quaternary codes has restricted the actual deployment of corresponding PMEPR mitigation techniques in cellular phone communications. To reduce the system complexity, in this paper we use two BPSK constellations to construct the Asterisk 16QAM. The proposed scheme only needs the binary Reed-Muller code, so the system complexity is reduced.
