 with one or more additional searchers. However, this is inefficient because the additional searchers make it necessary to increase the size of the receiver, add components which are used during only a portion of the time the receiver is in operation, and increase the power consumed by the receiver.
Therefore, it is an object of the present invention to provide a radio communication apparatus including a rake receiver which adaptively assigns a searcher operation and a finger operation in response to the characteristics of the transmission path existing at a given time between the base and mobile stations.
To accomplish these objectives, a radio communication apparatus is provided which comprises:
at least one combination searcher/finger unit operable to perform (1) a searcher operation for detecting signals on the reception paths and (2) estimating the strength of each of the signals, and a finger operation for outputting a demodulated symbol in response to a command signal. The radio communication apparatus is further provided with an assignment unit for generating the command signal to assign either the searcher operation or the finger operation of a combination searcher/finger unit based on at least one of the following conditions:
(1) the number of useful information containing reception paths which can be demodulated; or
(2) the number of neighboring base stations; or
(3) the total signal strength of the useful reception paths; or
(4) the reception error rate of the combined signal; or
(5) the reception modes having an initial synchronizing mode for synchronizing with one of the base stations, a call waiting-mode for waiting for a call from the synchronized base station and a communication mode for communicating to the synchronized base station. The leukocyte differentiation antigen CD33 is a 364 amino acid transmembrane glycoprotein with sequence homology to members of the sialoadhesin family, including myelin-associated glycoprotein and CD22, as well as sialoadhesin itself (S. Peiper, 2002, Leucocyte Typing VII, White Cell Differentiation, Antigens, Proceedings of the Seventh International Workshop and Conference, Oxford University Press, p. 777).
Expression of CD33 appears to be highly specific to the hematopoietic compartment, with strong expression by myeloid precursor cells (S. Peiper, 2002). It is expressed by myeloid progenitor cells such as CFU-GEMM, CFU-GM, CFU-G and BFU-E, monocytes/macrophages, granulocyte precursors such as promyelocytes and myelocytes although with decreased expression
with one or more additional searchers. However, this is inefficient because the additional searcher name it necessary to increase the size of the receiver, add components which are use during only a portion of the prison term the telephone receiver is in operation, and increase the power consumed by the receiver. 
 consequently, it is an object of the present invention to provide a radio communication apparatus including a pitch receiver which adaptively assigns a searcher process and a finger operation in response to the feature of the transmission path existing at a give time between the base and mobile stations. 
 To carry through these objectives, a radio communication apparatus is provided which comprises: 
 at least one combination searcher / finger unit functional to perform (1) a searcher operation for detecting signals on the reception paths and (2) estimating the lastingness of each of the signals, and a finger operation for outputting a demodulated symbol in response to a command signal. The radio communication apparatus is further provided with an assignment unit of measurement for generating the command signal to arrogate either the searcher process or the finger operation of a combination searcher / finger unit based on at least one of the follow conditions: 
 (1) the number of useful information check reception paths which can be demodulated; or 
 (2) the number of neighboring base stations; or 
 (3) the full signal strength of the useful reception paths; or 
 (4) the reception error pace of the combined signal; or 
 (5) the reception mood have an initial synchronizing mode for synchronizing with one of the base station, a call waiting - mode for waiting for a call from the synchronized base station and a communication modality for communicating to the synchronized foundation station. The leukocyte specialization antigen CD33 is a 364 amino acid transmembrane glycoprotein with sequence homology to members of the sialoadhesin family, including myelin - consociate glycoprotein and CD22, as well as sialoadhesin itself (S. Peiper, 2002, Leucocyte Typing VII, White Cell Differentiation, Antigens, Proceedings of the Seventh International Workshop and Conference, Oxford University Press, p. 777). 
 Expression of CD33 appears to be highly specific to the hematopoietic compartment, with solid expression by myeloid harbinger cells (S. Peiper, 2002). It is expressed by myeloid progenitor cells such as CFU - GEMM, CFU - GM, CFU - G and BFU - E, monocyte / macrophages, granulocyte precursors such as promyelocytes and myelocytes although with decreased construction
