PSEUDORANDOM SEQUENCE GENERATION FOR OFDM CELLULAR SYSTEMS

摘要

In one embodiment, a transmitter (105) includes a binary sequence generator unit (106) configured to provide a sequence of reference signal bits, wherein the sequence is an inseparable function of a cell identification parameter, a cyclic prefix mode corresponding to the transmitter and one or more time indices of the sequence. The transmitter (105) also include a mapping unit (107) that transforms the sequence of reference signal bits into a complex reference signal, and a transmit unit (108) configured to transmit the complex reference signal. In another embodiment, a receiver (110) includes a receive unit (111) configured to receive a complex reference signal and a reference signal decoder unit (112) configured to detect a sequence of reference signal bits from the complex reference signal, wherein the sequence is an inseparable function of a cell identification parameter, a cyclic prefix mode corresponding to a transmitter and one or more time indices of the sequence.
