摘要： In an OFDM mobile communications system, an algorithm for forming a preliminary estimate of the channel on pilot subcarriers is carried out. Based on this preliminary estimate, a channel property is estimated. This channel property is then used to decide whether to enter a mobile receiver mode or a stationary receiver mode. For example, in the mobile mode channel estimation is performed using only pilot symbols from the current symbol period, while in the static mode channel estimation is performed using pilot symbols from the current symbol period and pilot symbols from other symbol periods.

摘要： A method for detecting validity of downlink control information in telecommunication user equipment and a decoder and baseband receiver to perform the method are provided. The object of avoiding falsely detecting payload data and misinterpreting them is achieved by reverse encoding a bit output sequence of a Viterbi decoder; determining hard bits from a soft-bit input sequence of the decoder; determining a bit count of real received bits; comparing the reverse encoded bit stream to the determined hard bit stream and counting the number of mismatches to obtain an error count; comparing a bit error rate which is defined as a quotient of the error count and the bit count against a predefined threshold value; and rejecting the payload as invalid if said bit error rate is above said threshold value, even if a cyclic redundancy check of the payload gives a correct result.

摘要： The invention relates to a method and a device for operation of two wireless services whereas a first service is broadcasting signals within burst with known time distances between the bursts and a second service is transmitting signals at least between a first partner and a second partner. The problem to be solved by the invention is to enable a user to use applications of at least to services concurrently at the same time with the same device. The problem is solved by an operation of one and the same device which is receiving bursts in a first mode of the first service and is switched from the first mode into a mode of the second service during the time between the bursts of the service.
