摘要： The invention is a method and system for reducing the dynamic range of a signal input to a power amplifier in a CDMA forward-link transmission system. This is achieved by introducing a controllable amount of code-domain distortion to the data prior to spreading by Walsh codes. The amount of distortion is calculated by creating a data vector, applying a transform to the data vector to obtain a sequence, distorting the result to obtain a distorted sequence, applying an inverse transform to the distorted sequence to obtain a distorted data vector and comparing the distorted data vector to the original data, thereby to obtain the amount of code-domain distortion to be added to the data. The resultant, “corrected” spread-spectrum waveform can be controlled to the extent that it is guaranteed never to exceed a prescribed voltage range.

摘要： A method selects mobile station candidates for use with virtual multiple-input multiple-output (“V-MIMO”) in a communication system. The communication system includes at least one base station and a plurality of mobile stations. At least one downlink metric is determined for a first mobile station. The at least one downlink metric is used to determine eligibility for uplink V-MIMO candidate list selection. Responsive to determining that the first mobile station is eligible for uplink V-MIMO candidate list selection, the first mobile station is paired with a second mobile station eligible for uplink V-MIMO candidate list selection.
