Patent AT-E401695-T1: [Translated] CONTROL OF POWER RATIOS FOR IN-PHASE AND QUADRATURE CHANNELS IN A COMMUNICATIONS SYSTEM
A transmitter in a radiocommunications system such as a Wideband Code Division Multiple Access (WCDMA) communications system transmits one set of data on an in-phase (I-) channel and another set of data on a quadrature (Q-) channel. The transmitter generates a gain signal, ², and multiplies the digital data associated with the Q-channel by the gain signal, ². Complexity of the multiplication operation is reduced by limiting the gain signal, ², to a finite number of values that are exactly representable by a predefined number of bits, such as 4-bit values to the right of a binary radix point. Modulation inaccuracy associated with quantization of ² can be eliminated by utilizing the same quantized values of ² in all components within the radiocommunications system.
