摘要： A method and apparatus for transmitting/receiving a Random Access Channel (RACH) signal in a communication system. A User Equipment (UE) selects one of Contention Resolution (CR) channels allocated for collision detection, and transmits the selected CR channel and a connection request message to an Evolved Node B (E-NB), and receives a response signal from the E-NB. The UE transmits the RACH signal, if a collision indicator is included in the response signal. The E-NB receives from each of UEs a connection request message and a CR channel, decodes the connection request message, and detects a collision between the UEs using the CR channel. The E-NB generates a response signal to the connection request message according to the decoding result, generates a collision indicator according to the collision detection result, and transmits to the UEs at least one of the generated response signal, the generated collision indicator, and a unique ID of a corresponding UE.

摘要： A transmitter and receiver for fast frequency hopping based on a cyclic frequency hopping pattern in an orthogonal frequency division multiplexing system. The transmitter outputs a transmission signal vector having a plurality of samples. In the receiver, a first Fast Fourier Transform (FFT) processor transforms a first received signal vector into a second received signal vector of a frequency domain by using FFT. An equalizer multiplies the received signal vector by an inverse matrix of a channel matrix representing characteristics of a channel from the transmitter to the receiver. A modified IFFT processor transforms output of the equalizer by using IFFT, and multiplies IFFT outputs of a last stage of the modified IFFT processor by predetermined gains associated with the cyclic frequency hopping pattern of the transmitter. A second FFT processor transforms output of the modified IFFT processor by using FFT to output a recovered received signal vector.
