Abstract
Disclosed in a novel scheme to jointly reduce and trade-off Peak-to-Average Power Ratio (PAPR) and a Block Error Rate (BLER) using random network coding. To do this, the different representations of the input information block are generated using a special form of network coding matrices. Further, the encoded block puncturing is utilized to improve in the PAPR against a degradation in the BLER.
