The algebraic course challenge is a generalization of the shortest course challenge in graphs. numerous situations of this summary challenge have seemed within the literature, and comparable suggestions were independently came upon and rediscovered. The repeated visual appeal of an issue is proof of its relevance.

Random access and cell search (Levanon & Mozeson, 2004; LTE, 2009). A BTPA-based CE technique is discussed in great detail in Section 5. , 2006; 2005; 2003) to replace the TD redundancy with null samples or known/pre-determined sequences. , 2006; 2005; 2003). , 2000). Meanwhile, PRP-OFDM replaces the null samples originally inserted between any two OFDM blocks in ZP-OFDM by a known sequence. , 2006; 2005; 2003). , 2005). TDS-OFDM works similarly to the PRP-OFDM and also belongs to this category of CEs assisted by TD redundancy.
SC-FDMA has been chosen in the LTE specifications as a promising uplink transmission technique because of its low PAPR. , 2006). In practice, pilot signals or reference signals for CE in SC-FDMA systems are inserted to occupy whole sub-channels periodically in the time direction, which can be considered to be BTPA. In this section, the signal model and system description of a BTPA-based CE technique is studied. The material discussed in this section can be found, in part, in a previous study (Huang & Lin, 2010).
Rather than inserting a blank GI between any two consecutive OFDM symbols, which was the method employed in the previous study (Weinstein & Ebert, 1971), a cyclic extension of an OFDM block is inserted into the original GI as a prefix to an information-bearing OFDM block. The adopted cyclic prefix (CP) effectively converts the linear convolution of the transmitted symbol and the channel impulse response (CIR) into the cyclic convolution; thus, orthogonality among sub-carriers can be maintained with channel time-dispersion if the CP is sufficiently longer than the CIR.
