The cancellation module cancels the blocking signal by generating an injection signal representative of the blocking signal, combining the blocking signal with the injection signal to produce an error signal, updating the injection signal based on the error signal and using the injection signal to cancel the blocking signal from the amplified inbound RF signal.2011-03-03
20110051671Method and Apparatus for Transmitting Control Signal in Radio Communication System - A method and an apparatus of transmitting a control signal in a wireless communicatino system is provided. They generate a first-spread sequence by spreading a modulated sequence in the first slot by using a first orthogonal sequence, generate a second-spread sequence by spreading a modulated sequence in the second slot by using a second orthogonal sequence. The first spread sequence and the second spread sequence are transmitted in a subframe. A length of the first orthogonal sequence is shorter than a length of the second orthogonal sequence, the second orthogonal sequence is generated by removing at least one element included in the first orthogonal sequence, and the at least one element to be removed is identical in every index of the first orthogonal sequence.2011-03-03
