Abstract  Abstract

A TRANSMITTER IS 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 (101) AND ANOTHER SETOF DATA ON A QUADRATURE (Q-) CHANNEL (103). THE TRANSMITTER GENERATES A GAIN SIGNAL ß AND MULTIPLIES THE DIGITALDATA ASSOCIATED WITH THE Q-CHANNEL (103) BY THE GAIN SIGNAL ß. COMPLEXITY OF THE MULTIPLICATION OPERATION ISREDUCED BY LIMITING THE GAIN SIGNAL ß TO A FINITE NUMBER OF VALUES THAT ARE EXACTLY REPRESENTABLE BY APREDEFINED NUMBER OF BITS SUCH AS 4-BIT VALUES TO THE RIGHT OF A BINARY RADIX POINT. MODULATION INACCURACYASSOCIATED WITH QUANTIZATION OF ß CAN BE ELIMINATED BY UTILIZING THE SAME QUANTIZED VALUES OF ß IN ALLCOMPONENTS WITHIN THE RADIOCOMMUNICATIONS SYSTEM.(FIG. 3)
