... perform channel estimation. As shown in Figure 2, the channel estimator firstly performs channel frequency response estimation at pilot subcarriers. There are some channel estimation methods for ... the same performance with the conventional LMMSE channel estimation in terms of the normalized mean square error (NMSE) of channel estimation and bit error rate (BER). Secondly, the prop...

... innovative and instantaneously decodable, hence does not incur any delay. We note that a packet that is not transmitted yet or transmitted but not received by any receiver can be transmitted in an uncoded ... and instantaneously decodable for all the three receivers. On the other hand, one can verify that if we adopt a minimum coding strategy andsendpacketm 3 in the third transmission rou...

... of circuit speed and complexity, no register is shared by more than two reading channels and one writing channel. The consequence is that register access logic is simpler, smaller, and faster. 6. ... output uniform random number from this value. The logic used to generate values out of stages 2 and 3 is shown in Figure 2. The simplest form of parallelism for MT19937 is to perform stages 2...
