  • Publication number: 20130083872
    Abstract: Methods for coherent and non-coherent demodulation are disclosed. Embodiments herein relate to wireless communication systems, and more particularly, to demodulating block orthogonal codes in wireless communication systems. Coherent detection of signals provides improved performance at higher complexity of implementation, but it can be difficult to keep the frequency errors in a wireless communications receiver within the required limits for coherent detection. Embodiments disclosed enable means of using coherent demodulation for block orthogonal codes in the presence of high frequency errors, through the use of techniques of frequency prediction, estimation and correction. Further, it enables a low complexity frequency estimator which provides high estimation range and accuracy.

  • Patent number: 7965687
    Abstract: A method and a system for Multiple-Input-Multiple-Output (MIMO) communication in a wireless network are provided. According to the method, streams of the data of a user-equipment are communicated to a group of user-equipments that act as antennas for the user-equipment. The communication between the various user-equipments is through an Interlink. The data of the user-equipment is communicated with base stations by the user-equipment and the group of user-equipments in a single slot.

  • Publication number: 20060153322
    Abstract: A method and system for synchronization between a transmitter and a receiver in a communication system is provided. The receiver receives a plurality of signals from the transmitter. According to this method, a frequency burst is detected in the received signal at the receiver. The detected frequency burst is then validated on the basis of a synchronization burst in the received signal. Finally, the frequency and timing information present in the received signal is acquired for synchronization with the transmitter. The frequency and timing information is acquired on the basis of the validated frequency burst.
