Embodiment Construction

[0029] A method and apparatus processes multiple analog signals in a transceiver having multiple receive (Rx) antennas in a wireless communication system utilizing space diversity. By properly combining the analog signals for each Rx antenna, this approach allows reducing the number of front-end components such as filters, mixers and analog-to-digital converter (ADC) devices. Subsequently, the signals are digitally separated by a unique code. The benefits associated with this approach are at least threefold: reduced cost, area and power consumption of multi-antenna terminals. Additionally, proper parameter setting increases the signal quantization-to-noise ratio (SQNR) at the ADC output.

[0030] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that the various aspe...

Abstract

A method and apparatus processes a plurality of analog signals in a transceiver with multiple receive (Rx) antennas in a wireless communication system. By appropriate combining of the analog signals of each Rx antenna, this scheme allows a reduction in the number of the front end components, for example, filters, mixers and Analog to Digital Converter (ADC) devices. Subsequently, the signals are separated digitally by virtue of their unique code. The benefits associated with this scheme are at least threefold: reduced cost, area, and power consumption of a multiple antenna terminal. Additionally, proper parameter settings increase signal to Quantization Noise Ratio (SQNR) at the ADC output.

Description

[0001] Claim of priority under 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 058,159, filed June 2, 2008, entitled "MULTIPLEXING ARRANGEMENTS FOR MULTIPLE RECEIVE ANTENNAS," Said application is assigned to the present assignee and is hereby expressly incorporated herein by reference. technical field [0003] The present disclosure relates generally to communications, and more particularly to techniques for wirelessly receiving data packet communications at multiple receive (Rx) antennas. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth and transmit power). Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Div...
