Abstract
In [1], the throughput and access delay performance of the RACH in an orthogonal frequency division multiple access (OFDMA) system is analyzed. However, the analysis of access delay is incorrect. This note corrects the original equations and results show that the new equations correct the non-negligible error of the average access delay under the uniform backoff policy.
