Radio communications are often desirable for data and voice communications in an indoor environment. Wireless technology offers an improved mobility since the users are not confined to any particular location by wires. This paper investigates the use of Reed–Muller codes in an indoor wireless environment. Code combining is used to exploit the multiple signal copies resulting from the inherent frequency diversity of spread spectrum. The performance of Reed–Muller codes is compared with that of convolutional codes of similar rates and comparable decoding complexity. The complete weight distribution of various Reed–Muller codes is presented.
