In this paper, we propose memory reduction methods for IEEE 802.16e mobile station. Proposed methods are modulation encoder and decoder for uplink allocation, FIFO sharing architecture in downlink synchronizer and replacing frame memory for received signal storing with memory for preamble and FIFO for burst data. Comparison results show that the proposed methods reduce the memory size about 74.5%, 32.2% and 85.2% compared with conventional methods, respectively.
