Patent number: 8358713Abstract: In digital communication systems forward error correction coding techniques are typically used to improve the bit error rate performance. The receiver of the digital communication systems employs a decoding apparatus which may use Maximum A posteriori Probability (MAP) algorithm and its variations such as Logarithmic-MAP (Log-MAP), Maximum-Logarithmic-MAP (Max-Log-MAP). MAP decoding apparatus is commonly used as a key component in of decoder for error correcting codes such as convolutional codes and turbo codes. The MAP decoding apparatus computes likelihood estimates as the output. The present invention performs faster MAP decoding by computing likelihood estimates in parallel.Type: GrantFiled: September 10, 2008Date of Patent: January 22, 2013Inventor: Sarath Babu Govindarajulu

Patent number: 8260231Abstract: The present invention provides architectures and methods which use multiple radio receive chains in mobile devices to boost performance of the mobile devices. While a first set of the receive chains are assigned to a serving base station, another set of receive chains are dynamically allocated to neighbor base stations and/or to the serving base station depending upon present or expected system conditions and timing. A first synthesizer is configured to provide signals to the first and second set of receive chains. Other synthesizers are also configured to provide signals to the second set of receive chains. Thus, depending on the mode of operation, the second set of receive chains utilizes signals from a given synthesizer as needed. A priori data may be used to allocate specific receive chains to the serving base station, neighboring base stations or both. Unused synthesizers may be turned off to conserve power.Type: GrantFiled: January 9, 2012Date of Patent: September 4, 2012Inventors: Bhaskar Patel, Arumugam Govindswamy, Sarath Babu Govindarajulu
