The second scheme is fully diverse with any number of antennas and transmits at a rate of M log₂(P)/P bits PCU. The proposed codes permit to achieve different levels of compromise between complexity and performance since scheme 1 necessitates M-dimensional Maximum-Likelihood (ML) decoding while scheme 2 necessitates MP-dimensional decoding. We also present a comprehensive analysis on the enhancement in terms of the data rate achieved at a certain communication distance based on realistic indoor channel models and on an exact system model that takes inter-pulse-interference and intersymbol- interference into consideration.]]> 27 8 1331 1340 547 27 8 1341 1346 447 27 8 1347 1357 5556 27 8 1358 1366 1130 27 8 1367 1378 2798 27 8 1379 1389 912 27 8 1390 1399 2802 27 8 1400 1413 1103 27 8 1414 1424 489 27 8 1425 1432 512 -6) for pi/2-BPSK, QPSK, 8 PSK and 16 QAM are 13, 7, 0 and -6dB respectively. And the CCI rejection for similar modulation schemes are -18, -20, -26 and -29 respectively. Secondly, we have clarified the LOS-NLOS relationship of the ACI/CCI impact to system performance. ACI in multipath NLOS environment causes an additional 5 dB degradation to error performance as compared to ACI in the LOS environment. CCI on the other hand, has similar impact on error performance in both LOS and NLOS environment. Thirdly, we have clarified the relationship between modulation spectral efficiency and robustness against ACI/CCI. In an environment with no or low ACI/CCI, the maximum achievable throughput for pi/2-BPSK, QPSK, 8 PSK and 16 QAM in LOS environment are 1.2, 2.5, 3.8 and 5 Gbps respectively. In NLOS environment, the achievable throughput decreases to 1, 1.9, 2.8 and 3.8 Gbps respectively. As ACI/CCI increases, the throughput of higherorder modulation schemes such as 16 QAM decreases the most rapidly, followed by 8 PSK and QPSK. The throughput for pi/2-BPSK has the highest tolerance against increasing ACI/CCI, at the expense of lower maximum achievable throughput.]]> 27 8 1433 1442 851 27 8 1443 1452 581 27 8 1453 1465 1154 27 8 1466 1478 1677 -10 (0.2 times 10^-9)Joules/Bit by using variable transmit powers at different parts of the room. Finally, we study the problem of coverage due to blocking of the LoS (line of sight) path. To mitigate this problem we study the use of static reflectors and show that coverage in the entire room can indeed be maintained.]]> 27 8 1479 1487 2815 27 8 1488 1499 1725 27 8 1500 1506 1337 27 8 1507 1519 503 27 8 c3 c3 64 27 8 c4 c4 58
