Abstract:

A Linear Minimum Mean Square Error Parallel Interference Cancellation (LMMSEPIC) scheme was proposed to cancel Multiple Access Interference (MUI) in uplink Orthogonal FrequencyDivision Multiple Access (OFDMA). First, the Linear Minimum Mean Square Error (LMMSE) algorithm was derived to estimate the MUI. Then, the advantage of an iterative Parallel Interference Cancellation (

Key words: communication, orthogonal frequency division multiple access(OFDMA), carrier frequency offset(CFO), parallel interference cancellation(PIC), linear minimum mean square error(LMMSE)
