Transmission power control for multiple codes multiple antennas system |
摘要 |
Disclosed is a wireless communication apparatus and method for a multiple transmit and receive antenna system using multiple codes. In suggested detection algorithm, a successive interference cancellation (SIC) scheme is employed in both an antenna domain and a code domain by successively canceling multi-code interference (MCI). An effective transmit power allocation method suitable for the detection algorithm is suggested. Transmit power allocated to each code is calculated. The transmit power is determined as a simple ratio of power of a certain signal to power of a next code signal. Based on the calculated code transmit power, transmit power for each transmit antenna is allocated. Thus, information about transmit power calculated at a receive end is feedback to a transmit end through a feedback channel. |
