    摘要: A noise and interference power measurement apparatus for an antenna diversity system that services a plurality of users with an array antenna having a plurality of antenna elements. A channel estimator estimates a channel impulse response for a radio channel corresponding to a predetermined plurality of regularly spaced direction-of-arrival (DOA) values. A data estimator estimates the received data using a received signal and a system matrix. A quantizer quantizes the estimated data. An interference and noise calculator calculates noise vectors at the respective antenna elements by removing from the received signal an influence of the quantized data to which the system matrix is applied, calculates an estimated noise matrix at the plurality of antenna elements, calculates interference power by auto-correlating the estimated noise matrix, and calculates noise and interference power based on the interference power.

    摘要: A method and apparatus in a UE for detecting active channelization codes including channelization codes used by other UEs, which are different from at least one channelization code assigned to the UE, for transmission/reception to/from a Node B in an assigned time slot in a mobile communication system, where each of time slots of a radio channel frame is identified by a plurality of code channels, each having a unique channelization code. Accordingly, a channelization code set is formed to include a predetermined number of channelization codes to be searched, code channel data corresponding to the channelization codes is detected from a received signal, the code power of the code channel data is measured and compared with a predetermined threshold, and channelization codes having code power values exceeding the threshold are selected as active channelization codes.

    摘要: A joint detection reception apparatus and method, which are utilized irrespective of a length of an orthogonal code in a TD-CDMA communication system. The joint detection reception method for creating a system matrix associated with a joint detection receiver in the same time slot includes the steps of a) repeating and partitioning individual channelization codes having variable lengths, and creating channelization code blocks having the same lengths, b) performing a convolution operation between the repeated and partitioned channelization code blocks and a channel impulse response, and acquiring combined impulse responses, c) grouping the combined impulse responses to construct sub-block matrices for a joint detection system, d) arranging the sub-block matrices for the joint detection system to be shifted by a predetermined column distance, and constructing a joint detection system matrix, and e) extending the joint detection system matrix to a squared-format matrix to create a block-circulant squared matrix.
