20120220287 | METHODS AND SYSTEMS FOR SLOW ASSOCIATED CONTROL CHANNEL SIGNALING - Methods and systems for slow associated control channel signaling are disclosed. An example method for securing communications in a mobile network disclosed herein comprises transmitting a first variant of a message of a first type on a first slow associated control channel (SACCH) before ciphering is started on the first SACCH, and after ciphering is started on the first SACCH, transmitting a second variant of the message of the first type on the first SACCH, and subsequently transmitting the second variant of the message of the first type on the first SACCH, wherein the subsequently transmitted second variant of the message of the first type is the next transmitted message of the first type on the first SACCH. | 08-30-2012 |
20130034054 | METHOD AND SYSTEM FOR FORMATTING CYCLIC PREFIX/POSTFIX IN A MOBILE COMMUNICATION SYSTEM - A method and transmitter, the method generating a burst containing a first data portion and a second data portion surrounding a training sequence; and appending to the burst a cyclic prefix and a cyclic postfix. Further a receiver on a network element, the receiver configured to: receive a burst containing a cyclic prefix, a cyclic postfix and a data portion; remove at least one of the cyclic prefix or the cyclic postfix; transform the data portion with a discrete Fourier transform; estimate the channel frequency response and modulation of the burst; undo an effect of a channel on the data portion by using the estimated channel frequency response of the channel on the transformed data; use an inverse discrete Fourier transform on the result of the equalizing step; and further process the output of the equalization step to decode the transmitted bits. | 02-07-2013 |
