... always mapped into the first OFDM symbol of the first slot of each subframe. For the normal CP duration, the PHICH is also mapped into the first OFDM symbol of the first slot of each subframe. On the ... code of length 4, and (3,1) repetition code in the case of normal CP [1, 2]. In case of extended CP, a maximum of 4 HI channels are allowed in a PHICH group, and hence a spreading...

... is higher. If the resolution of the samples of the desired subband is to be of the order of 5 bits as before, the ADC resolution re- quired depends on the level of adjacent channel interference (ACI) ... mentioned earlier, the number of symbols in mDECT-SB in a full slot is reduced by a factor of four, from 480 to 120 symbols. The efficiency of TDMA can be poor if the TDMA overh...

... where the number of delays is limited such as the case of complex programmable logic devices (CPLDs), or low-power designs. Architecture of the Kalman filter is independent of oversampling ratio ... is about the same. In conclusion, the advantages of Kalman filter over the other filters are (i) the filter implementation is indepen- dent of the oversampling ratio and thus suitable fo...
