Unequal Power Allocation and Generalized ESE for ODMA-Based Unsourced Random Access

On-off division multiple access (ODMA) has emerged as a state-of-the-art unsourced random access (URA) scheme for massive machine-type communications. However, its performance is constrained by equal power allocation, which lacks a natural decoding order for successive interference cancellation, and by the elementary s...
