    摘要: A channel estimation method in a wireless communication system based on multicarrier-code division multiple access (MC-CDMA) using frequency interleaving. A transmitter generates transmission symbols using a pilot signal (P) and an inverted pilot signal (−P) according to subcarriers on which spread symbols generated from a spectrum spreading operation are sent, performs an interleaving operation for the transmission symbols in a frequency domain, and transmits a result of the interleaving operation. A receiver extracts the pilot signal (P) and inverted pilot signal (−P) included in the transmission symbols and performs channel estimation.

    摘要: Disclosed is a method for estimating a channel using a pilot signal in a wireless communication system based on multi-carrier multiple access. A transmission side generates a pilot symbol correlated with spread data symbols which is included in a spread symbol generated through a band spreading, inserts the pilot symbol into the spread symbol, and transmits the spread symbol. A reception side receives the spread symbol and detects the pilot signal by using the spread data symbols and pilot symbol included in the spread symbol. Therefore, it is possible to simultaneously obtain both the position optimization of a pilot symbol, according to a channel state such as a correlation band or correlation time (which is an advantage over the pilot-tone-based channel estimation method), and a noise reduction effect by the averaging procedure (which is an advantage over the pilot-channel-based channel estimation method), so that the accuracy of channel estimation can be improved.

    摘要: An apparatus and method for transmitting MAP by a base station in a wireless mobile communication system using a frame that includes a plurality of mini frames occupying a specific time period, each of the mini frames including a plurality of Resource Blocks (RBs) occupying a specific frequency band are provided. A number of RBs to be occupied by a data burst to be transmitted is determined. A first variable indicative of a number of mini frames to be occupied by the data burst is determined based on a resource amount corresponding to the number of RBs and an available resource amount of the mini frame. A second variable is determined based on the number of RBs and the first variable. MAP is transmitted that includes the first variable, the second variable, and information indicating RBs where a resource is allocated in a mini frame first located in a time domain among the mini frames to be occupied by the data burst. Each of the RBs where the resource is allocated represents an RB where one of packets segmented from the data burst is allocated.
