Abstract: A communication device and a method of controlling the same. The communication device includes at least one receiver configured to connect to a first antenna for receiving a first signal and a second antenna for receiving a second signal; and a processor electrically coupled to the at least one receiver, wherein the processor is configured to measure received signal strengths of the first signal and the second signal based on calibration operation for the first antenna and the second antenna, select one of the first antenna and the second antenna based on the measured received signal strengths, and control the at least one receiver to receive a signal through the selected one of the first antenna and the second antenna.

Abstract: A method for detecting a signal by a signal receiving apparatus is provided. The method includes detecting a part of block diagonal matrices included in a diagonal matrix based on at least one channel impulse response (CIR) for a received signal, detecting remaining block diagonal matrices excluding the part of block diagonal matrices from among block diagonal matrices included in the diagonal matrix, estimating modulation symbols from the received signal based on the diagonal matrix, generating a block diagonal matrix by multiplying one of second matrices included in a first matrix, which is generated by applying a circular extension scheme to a fourth matrix including third matrices, by a fast Fourier transform (FFT) matrix, generating a third matrix for one of the estimated modulation symbols, the third matrix includes vectors for channelization codes, and generating a vector based on the channelization codes or the at least one CIR.
