Example embodiments of the present invention concatenate code blocks for turbo codes I and II. Example embodiments of the present invention may also concatenate code blocks for convolutional code. Example embodiments of the present invention also disclose a system to concatenate the code blocks.

摘要： Example embodiments include methods of interference cancellation at NodeB receivers of baseband antenna signals including physical channels. The methods include canceling interference from a received baseband antenna signal by removing a reconstructed baseband signal from the processed received baseband antenna signal. The processed reconstructed baseband signal includes users whose physical data channel signals were successfully decoded. Methods also include removing interference from a received baseband signal to form an interference cancelled baseband signal that will be processed by the receiver. The interference cancelled baseband signal is the received baseband antenna signal minus users' signal interference contributions whose demodulated physical data channel signals have a determined user symbol energy value that exceeds a threshold. Methods further include removing interference from a user's signal to be error corrected. The interference is symbol interference from an earlier successfully decoded user's symbols. The user symbol interference is determined by cross correlations.

摘要： A method of synchronizing with an uplink channel and a method of determining a propagation delay in a wireless communications system are provided. In the example method of synchronizing, a propagation delay between a target base station and a mobile station is calculated. Then, the calculated propagation delay is sent to the target base station. In the example method of determining a propagation delay, a first signal is received indicating a first measured chip offset between a downlink channel of a serving base station and a pilot signal of the target base station. A second signal indicating a second measured chip offset between an uplink channel of the mobile station and a pilot signal of the target base station is then received. A propagation delay between the target base station and the mobile station is calculated based at least in part on the first and second measured chip offsets.
