CYCLIC SHIFT MAPPER, TRANSMITTER OF WIRELESS COMMUNICATION AND RECEIVER OF WIRELESS COMMUNICATION

摘要

PURPOSE: A cyclic shift mapper, a transmitter of wireless communication, and a receiver of wireless communication are provided to reduce the structure and the calculation amount of a transmitter-receiver by reducing the structure and the calculation amount of a cyclic shift operation unit. CONSTITUTION: A cyclic shift mapper(10) includes an input buffer(110), a switch(120), and an output buffer(130). The input buffer temporarily stores input data. The input data is cyclic-shifted as much as the multiple of a time interval pre-set by the switch. An output buffer temporarily stores the cyclic-shifted data.
