Figure 9 shows the block diagram of horizontal coded layered structure MIMO OFDM system with two transmit and two receive antennas.
Simulation result shows the bit error rate (BER) of horizontal coded LST architecture OFDM system having 32 sub-carriers, with two transmit and two receive antennas over a Rayleigh fading with additive white Gaussian noise (AWGN) channel.
In this paper, a technique for layered MIMO OFDM is proposed with low complexity that uses the RLS algorithm for channel estimation.
Where conventional single-carrier transmission schemes send only one signal at a time using one radio frequency, OFDM
sends multiple high-speed signals concurrently on different frequencies.
Now fully revised and updated, with more than 300 pages of new material, this new edition presents the wide range of recent developments in the field and places particular emphasis on the family of coded modulation aided OFDM and CDMA schemes.
Part III - details the advanced intricacies of adaptive versus space-time block- and trellis-coded OFDM and MC-CDMA
The re-designed OFDM
engine in Libra MX supports four times as many voice calls as other similar products on the market.
