Method, system and apparatus for the control of transmit diversity

摘要

A method, apparatus and system for modifying a transmit diversity signal comprising receiving at least one input parameter, calculating at least one virtual parameter based on the at least one input parameter, converting the at least one virtual parameter into an actual parameter, and modifying a transmit diversity signal based on the actual parameter. Variations of the invention are possible, including mapping the input parameter to an actual parameter by various methods, for example, quantization, hysteresis and other methods. Embodiments of the invention may include an apparatus adapted to modify a transmit diversity signal comprising a processor to calculate at least one virtual parameter based on at least one input parameter, convert said at least one virtual parameter to an actual parameter, and modify said transmit diversity signal based on said actual parameter.

1. A method for modifying a transmit diversity signal comprising:
receiving at least one input parameter; calculating at least one virtual parameter based on said at least one input parameter; converting said at least one virtual parameter into an actual parameter; and modifying a transmit diversity signal based on said actual parameter, wherein said actual parameter has a discrete value having lower resolution than said at least one virtual parameter, wherein converting said at least one virtual parameter into said actual parameter comprises mapping any of a plurality of virtual parameter values to a single actual parameter value, and wherein converting said at least one virtual parameter into said actual parameter comprises truncating said virtual parameter to obtain said actual parameter value, where the truncation is performed according to the formula:
Φact=b*floor((Φvirt+a/b), where Φvirt is a virtual parameter, Φact is an actual parameter, and a and b are selected numerical values.
