Abstract

Methods, systems, and devices for wireless communication are described. A wireless device may generate a coded pseudorandom using an encoder that implements error detection and/or error correction techniques. A bit sequence of information bits may be segmented into a plurality of bit groups, and each bit group may be mapped to a respective symbol to generate a plurality of ordered information symbols. The plurality of ordered information symbols may be encoded (e.g., by the encoder) to generate a plurality of codewords. Each codeword may be demapped to generate a plurality of sequences that are multiplexed to generate the pseudorandom sequence. A signal that is generated based on the pseudorandom sequence may be transmitted by the wireless device. In some examples, the wireless device may generate a reference signal based on orthogonal or pseudo-orthogonal random sequences generated by applying an orthogonal cover code to a pseudorandom sequence.
